1 00:00:00,000 --> 00:00:00,000 Hello guys. 2 00:00:00,000 --> 00:00:03,000 We are going to continue the discussion with respect to Python. 3 00:00:03,000 --> 00:00:05,000 And in this video we are going to talk about loops. 4 00:00:05,000 --> 00:00:10,000 Already in our previous video we have uh, we have seen a lot of examples with respect to conditional 5 00:00:10,000 --> 00:00:16,000 statements like if Elif else and we have seen multiple examples out there right now in loops, uh, 6 00:00:16,000 --> 00:00:22,000 we will be discussing about what are the different types of loop we usually use in Python programming 7 00:00:22,000 --> 00:00:27,000 language, like for loop while loop, uh, loop control statements like break, continue, and pass. 8 00:00:27,000 --> 00:00:31,000 Then we'll be discussing about nested loops, and then we'll be seeing like all these things. 9 00:00:31,000 --> 00:00:35,000 We will be seeing much more in with the help of practical examples. 10 00:00:35,000 --> 00:00:39,000 And what are the common errors we usually face and how to avoid those errors. 11 00:00:39,000 --> 00:00:42,000 So all these things will be discussing in this particular video. 12 00:00:42,000 --> 00:00:48,000 So first of all let's go ahead and work with for loop with a simple, uh, you know, syntax. 13 00:00:48,000 --> 00:00:53,000 So in order to write a for loop right you need to understand what a for loop is. 14 00:00:53,000 --> 00:00:55,000 A for loop is a loop, right? 15 00:00:55,000 --> 00:00:58,000 It is used to iterate over a sequence of numbers. 16 00:00:58,000 --> 00:00:58,000 Okay. 17 00:00:58,000 --> 00:01:05,000 So let's say I will give one example like for I okay I is just a temporary variable right now in let's 18 00:01:05,000 --> 00:01:07,000 say I want to create a sequence of numbers. 19 00:01:07,000 --> 00:01:12,000 Now in order to create a sequence of numbers, uh, I will show you with the help of range. 20 00:01:12,000 --> 00:01:12,000 Okay. 21 00:01:12,000 --> 00:01:14,000 So what exactly is range? 22 00:01:14,000 --> 00:01:14,000 Okay. 23 00:01:14,000 --> 00:01:18,000 So let's say in this particular range I give five elements. 24 00:01:18,000 --> 00:01:20,000 I basically want five elements over here. 25 00:01:20,000 --> 00:01:24,000 So this is turn actually help us to generate numbers between 0 to 5. 26 00:01:24,000 --> 00:01:24,000 Right. 27 00:01:24,000 --> 00:01:30,000 So here you can see that hey I'm getting a range uh between 0 to 5 over here. 28 00:01:30,000 --> 00:01:36,000 And let's say I want to just display all these numbers inside this right range is just giving us a sequence 29 00:01:36,000 --> 00:01:37,000 of numbers between 0 to 5. 30 00:01:37,000 --> 00:01:42,000 But if I want to iterate through this, all the numbers I can basically use for loop. 31 00:01:42,000 --> 00:01:46,000 So if I write for I in range five, right. 32 00:01:46,000 --> 00:01:52,000 And here if I go ahead and print I right now, you'll be seeing that after every iteration. 33 00:01:52,000 --> 00:01:58,000 First of all, when we are looping inside this sequence of numbers between 0 to 5, first it will go 34 00:01:58,000 --> 00:01:59,000 ahead and display zero. 35 00:01:59,000 --> 00:02:01,000 Then it will go ahead and display one. 36 00:02:01,000 --> 00:02:06,000 That basically means after every iteration, this number is basically getting incremented and it is 37 00:02:06,000 --> 00:02:08,000 traversing through all this range of numbers. 38 00:02:08,000 --> 00:02:14,000 One important thing that you should understand that since I've used range between 0 to 5, the last 39 00:02:14,000 --> 00:02:15,000 number is not going to get included. 40 00:02:15,000 --> 00:02:20,000 So that is the reason you can see zero is here, one is here, two is here, three is here, and four 41 00:02:20,000 --> 00:02:20,000 is here. 42 00:02:20,000 --> 00:02:21,000 Right. 43 00:02:21,000 --> 00:02:24,000 But the total number of elements is five over here and here. 44 00:02:24,000 --> 00:02:28,000 Uh, in short I've spoken about for loop and range as a function. 45 00:02:28,000 --> 00:02:28,000 Okay. 46 00:02:28,000 --> 00:02:34,000 So range as a function is also given Let's say I want to probably use for loop with different range 47 00:02:34,000 --> 00:02:34,000 of numbers. 48 00:02:34,000 --> 00:02:34,000 Right. 49 00:02:34,000 --> 00:02:40,000 Let's say if I go ahead and write one comma six, that basically means I want the number between 1 to 50 00:02:40,000 --> 00:02:40,000 6. 51 00:02:40,000 --> 00:02:42,000 Six is the last number. 52 00:02:42,000 --> 00:02:47,000 So we are not going to include it because at the end of the day, with respect to Python, whenever 53 00:02:47,000 --> 00:02:50,000 we are seeing indexing right, it always starts with zero, right. 54 00:02:50,000 --> 00:02:53,000 So uh, I'll talk more about it as I go ahead. 55 00:02:53,000 --> 00:02:57,000 Now, if I go ahead and execute this here, you'll be able to see one is getting displayed, two is 56 00:02:57,000 --> 00:03:00,000 getting displayed, three is getting displayed, four is getting displayed, five is getting displayed. 57 00:03:00,000 --> 00:03:07,000 So I can also call all my range of numbers with respect to or by giving a numbers between one number 58 00:03:07,000 --> 00:03:08,000 to the other number itself. 59 00:03:08,000 --> 00:03:13,000 Right now let me just give you more examples over here by using range. 60 00:03:13,000 --> 00:03:22,000 So if I go ahead and write range a range of one comma ten And let me just go ahead and give some third 61 00:03:22,000 --> 00:03:23,000 parameter. 62 00:03:23,000 --> 00:03:23,000 Right. 63 00:03:23,000 --> 00:03:27,000 So third parameter over here you'll be able to see that it is something called a step. 64 00:03:27,000 --> 00:03:29,000 Now see see the syntax. 65 00:03:29,000 --> 00:03:32,000 It shows start as the first parameter inside range function. 66 00:03:32,000 --> 00:03:34,000 Then you have the stop parameter. 67 00:03:34,000 --> 00:03:36,000 Then you have the step parameter okay. 68 00:03:36,000 --> 00:03:39,000 By default step parameter is usually given as one. 69 00:03:39,000 --> 00:03:44,000 Now start I'm saying hey start from one end till ten Right end before ten. 70 00:03:44,000 --> 00:03:46,000 I'll not say till ten, but before ten. 71 00:03:46,000 --> 00:03:49,000 And use the step size as one. 72 00:03:49,000 --> 00:03:51,000 That basically means only increment one number at a time. 73 00:03:51,000 --> 00:03:56,000 So if I go ahead and execute it, this will basically give me a range of value between 1 to 10. 74 00:03:56,000 --> 00:03:57,000 But and the step size will be one. 75 00:03:57,000 --> 00:04:00,000 Right now let me just go ahead and make it two okay. 76 00:04:00,000 --> 00:04:04,000 So here you can see that I'm starting from one before ten. 77 00:04:04,000 --> 00:04:04,000 It will stop. 78 00:04:04,000 --> 00:04:05,000 And here the range is two. 79 00:04:05,000 --> 00:04:08,000 That basically means the two numbers will get incremented. 80 00:04:08,000 --> 00:04:10,000 Now let me do one thing. 81 00:04:10,000 --> 00:04:10,000 Okay. 82 00:04:10,000 --> 00:04:16,000 Let me just write one over here and let me use a for loop again for I in range of this. 83 00:04:16,000 --> 00:04:18,000 And let me go ahead and print I. 84 00:04:18,000 --> 00:04:18,000 Okay. 85 00:04:18,000 --> 00:04:22,000 Now when I'm printing I you'll be able to see that what I'm actually getting. 86 00:04:22,000 --> 00:04:24,000 123456789. 87 00:04:24,000 --> 00:04:27,000 Now let me make this change from step size 1 to 2. 88 00:04:27,000 --> 00:04:28,000 Now what will happen? 89 00:04:28,000 --> 00:04:33,000 See, after one directly three will get displayed because we are going to skip one number. 90 00:04:33,000 --> 00:04:36,000 So it is just going to jump two steps ahead right now. 91 00:04:36,000 --> 00:04:37,000 See this. 92 00:04:37,000 --> 00:04:41,000 So now I can see 13579 right. 93 00:04:41,000 --> 00:04:46,000 So I am not probably traversing to each and every number, but instead I have given a step size of two. 94 00:04:46,000 --> 00:04:48,000 So it is jumping two numbers ahead. 95 00:04:48,000 --> 00:04:50,000 And that is how it is basically getting printed. 96 00:04:50,000 --> 00:04:52,000 Let me just show you one more example. 97 00:04:52,000 --> 00:04:59,000 Let's say that I want all the numbers between, um, 10 to 1. 98 00:04:59,000 --> 00:05:03,000 But now this time I will use a step size of minus one. 99 00:05:03,000 --> 00:05:07,000 Now what it is going to do, it is going to display a number between 10 to 1. 100 00:05:07,000 --> 00:05:09,000 And step size will be minus one. 101 00:05:09,000 --> 00:05:12,000 That basically means after ten it will become nine, then eight, then seven. 102 00:05:12,000 --> 00:05:12,000 See this. 103 00:05:12,000 --> 00:05:20,000 So here you can see 910 987654321 is not getting displayed as we know that last number will be skipped 104 00:05:20,000 --> 00:05:20,000 before this. 105 00:05:20,000 --> 00:05:22,000 all the numbers will be displayed. 106 00:05:22,000 --> 00:05:25,000 One more example that we if I really want to show it to you. 107 00:05:25,000 --> 00:05:26,000 So here you can see minus two. 108 00:05:26,000 --> 00:05:27,000 If I'm using minus two. 109 00:05:27,000 --> 00:05:31,000 So ten 86542642. 110 00:05:31,000 --> 00:05:31,000 Right. 111 00:05:31,000 --> 00:05:34,000 So I hope you have got an idea with respect to for loops. 112 00:05:34,000 --> 00:05:37,000 And with the help of range how we can actually move. 113 00:05:37,000 --> 00:05:38,000 Okay. 114 00:05:38,000 --> 00:05:42,000 Now let me show you with respect to strings I hope everybody has learned strings. 115 00:05:42,000 --> 00:05:43,000 Right. 116 00:05:43,000 --> 00:05:45,000 So strings uh how to properly create string. 117 00:05:45,000 --> 00:05:48,000 Let's say that this is my string okay. 118 00:05:48,000 --> 00:05:49,000 This is my string. 119 00:05:49,000 --> 00:05:51,000 And here I am going to write Krish Nayak. 120 00:05:51,000 --> 00:05:52,000 Okay. 121 00:05:52,000 --> 00:05:58,000 Now if I want to traverse to this particular string now see, one amazing thing about this data structure 122 00:05:58,000 --> 00:06:01,000 called a string is that we can traverse to each and every character over here. 123 00:06:01,000 --> 00:06:09,000 So if I go ahead and write for I in str, okay, and uh, for I in str. 124 00:06:09,000 --> 00:06:12,000 And if I just go ahead and print I okay. 125 00:06:12,000 --> 00:06:14,000 So string is basically a data structure. 126 00:06:14,000 --> 00:06:15,000 It is just nothing. 127 00:06:15,000 --> 00:06:17,000 But it is a collection of characters. 128 00:06:17,000 --> 00:06:20,000 Right now if I'm going to print over here, here you can see k r I s h. 129 00:06:20,000 --> 00:06:22,000 Then again space and I k right. 130 00:06:22,000 --> 00:06:27,000 Let's say that I, I'm traversing to this particular string. 131 00:06:27,000 --> 00:06:32,000 And I also want to do something like I may have a sentence I may have a paragraph. 132 00:06:32,000 --> 00:06:34,000 So based on that also I can print it over here. 133 00:06:34,000 --> 00:06:34,000 Right. 134 00:06:34,000 --> 00:06:40,000 Just to give you an idea what exactly this is, uh, because string is a collection of characters, 135 00:06:40,000 --> 00:06:41,000 right? 136 00:06:41,000 --> 00:06:42,000 It is a collection of characters. 137 00:06:42,000 --> 00:06:43,000 And we can also traverse thing. 138 00:06:43,000 --> 00:06:49,000 So the for loop main functionality is that whenever you have any collection items, like any collection 139 00:06:49,000 --> 00:06:54,000 data structure, you can traverse through it very much easily by just using a for loop. 140 00:06:54,000 --> 00:06:54,000 Right. 141 00:06:54,000 --> 00:06:56,000 So I've just given you an idea about it. 142 00:06:56,000 --> 00:07:01,000 But as we go ahead, we'll be seeing more complicated example, uh, as we go ahead. 143 00:07:01,000 --> 00:07:01,000 Right. 144 00:07:01,000 --> 00:07:05,000 But just to understand the basic example, this is what a for loop is all about. 145 00:07:05,000 --> 00:07:09,000 Now let's go ahead and discuss about something called as while loop okay. 146 00:07:09,000 --> 00:07:11,000 So while loop. 147 00:07:11,000 --> 00:07:15,000 So now let's see something about while loop. 148 00:07:16,000 --> 00:07:18,000 So now I have while loop okay. 149 00:07:18,000 --> 00:07:20,000 Now with respect to while loop right. 150 00:07:20,000 --> 00:07:28,000 If I really want to give a small definition, this while loop is nothing, but it continues to execute 151 00:07:28,000 --> 00:07:31,000 as long as the condition is true. 152 00:07:31,000 --> 00:07:36,000 Okay, that basically means unless and until this while loop whatever condition I'm writing in while 153 00:07:36,000 --> 00:07:39,000 loop, it is true it is just going to execute it. 154 00:07:39,000 --> 00:07:40,000 Okay, now let me do one thing. 155 00:07:40,000 --> 00:07:43,000 Let me create a temporary variable called as count. 156 00:07:43,000 --> 00:07:44,000 Okay. 157 00:07:44,000 --> 00:07:45,000 Count okay. 158 00:07:45,000 --> 00:07:52,000 Now with respect to this particular count, let me just go ahead and write while count is less than 159 00:07:52,000 --> 00:07:52,000 five. 160 00:07:54,000 --> 00:07:54,000 Okay. 161 00:07:54,000 --> 00:07:57,000 And now I have gone inside my while loop. 162 00:07:57,000 --> 00:07:59,000 Uh, while block or while loop over here. 163 00:07:59,000 --> 00:08:05,000 So I'm putting this particular condition unless until this count is not is less than five. 164 00:08:05,000 --> 00:08:07,000 Just go ahead and print it. 165 00:08:07,000 --> 00:08:08,000 Okay. 166 00:08:08,000 --> 00:08:11,000 Let's say I'm going to print the count okay. 167 00:08:11,000 --> 00:08:11,000 Okay. 168 00:08:11,000 --> 00:08:17,000 And after this, if I'm executing C, uh, I also need to increment the count over here. 169 00:08:17,000 --> 00:08:20,000 So I will go ahead and write count plus one okay. 170 00:08:20,000 --> 00:08:24,000 So what I'm doing unless and until this count is less than five, I'm going to print the count. 171 00:08:24,000 --> 00:08:28,000 And for every iteration, because we have initially initialized, count is equal to zero. 172 00:08:28,000 --> 00:08:31,000 For every iteration I am writing, count is equal to count plus one. 173 00:08:31,000 --> 00:08:34,000 Okay, now see what will happen if I execute this. 174 00:08:34,000 --> 00:08:36,000 You'll be seeing that zero is getting displayed. 175 00:08:36,000 --> 00:08:38,000 Initially, I will be having zero. 176 00:08:38,000 --> 00:08:40,000 So when I write while count is less than five, this is true. 177 00:08:40,000 --> 00:08:42,000 It is just going to print the count. 178 00:08:42,000 --> 00:08:43,000 So I'm going to get zero over here. 179 00:08:43,000 --> 00:08:46,000 And then it is going to increment the count. 180 00:08:46,000 --> 00:08:49,000 Now my temporary variable count will have one value right? 181 00:08:49,000 --> 00:08:54,000 I'll not say temporary, but uh my count value from this zero has got incremented to one. 182 00:08:54,000 --> 00:08:57,000 Then again this file while loop will run. 183 00:08:57,000 --> 00:08:57,000 Why? 184 00:08:57,000 --> 00:09:00,000 It will run because this condition is still true, right? 185 00:09:00,000 --> 00:09:03,000 So now here you can see when one is less than five. 186 00:09:03,000 --> 00:09:05,000 So one is obviously less than five in the second loop. 187 00:09:05,000 --> 00:09:06,000 So again this will get executed. 188 00:09:06,000 --> 00:09:08,000 Then again this will get incremented. 189 00:09:08,000 --> 00:09:09,000 Then again it will go to the next loop. 190 00:09:09,000 --> 00:09:11,000 Then this will become 234. 191 00:09:11,000 --> 00:09:12,000 Then. 192 00:09:12,000 --> 00:09:15,000 But once it becomes five right. 193 00:09:15,000 --> 00:09:17,000 While five is less than five now this becomes false. 194 00:09:17,000 --> 00:09:19,000 It is just going to come outside the loop, right? 195 00:09:19,000 --> 00:09:24,000 So that is how you are getting displayed with 01234. 196 00:09:24,000 --> 00:09:24,000 Right. 197 00:09:24,000 --> 00:09:30,000 So this is a simple way of probably displaying or understanding about the while loop. 198 00:09:30,000 --> 00:09:30,000 Okay. 199 00:09:30,000 --> 00:09:36,000 Uh, I may also write something like this while okay let's go ahead and write. 200 00:09:36,000 --> 00:09:38,000 Count is equal to zero okay. 201 00:09:40,000 --> 00:09:48,000 Count is equal to zero while count while count. 202 00:09:49,000 --> 00:09:51,000 Percentile two is double equal to zero. 203 00:09:52,000 --> 00:09:52,000 Okay. 204 00:09:52,000 --> 00:09:54,000 So now see this condition. 205 00:09:54,000 --> 00:09:59,000 What I'm saying while count percentile two is double equal to zero. 206 00:09:59,000 --> 00:10:04,000 If this is true right I will probably go ahead and print the count over here. 207 00:10:04,000 --> 00:10:05,000 Right. 208 00:10:05,000 --> 00:10:05,000 Right. 209 00:10:05,000 --> 00:10:11,000 And let's say that I will go ahead and or let me do one thing, okay. 210 00:10:11,000 --> 00:10:13,000 If I'm starting from count is equal to zero. 211 00:10:13,000 --> 00:10:17,000 And this condition is basically to check whether a number is a even number or not. 212 00:10:17,000 --> 00:10:17,000 Right. 213 00:10:17,000 --> 00:10:21,000 So if I just go ahead and execute it, how many times this will get displayed. 214 00:10:21,000 --> 00:10:23,000 See zero is getting displayed over here. 215 00:10:23,000 --> 00:10:23,000 Right. 216 00:10:23,000 --> 00:10:25,000 And it is continuously getting displayed. 217 00:10:25,000 --> 00:10:26,000 I'll stop this. 218 00:10:26,000 --> 00:10:28,000 See because I have not written any condition over here. 219 00:10:28,000 --> 00:10:29,000 So let me just go ahead and write. 220 00:10:29,000 --> 00:10:32,000 Count is equal to count plus one okay. 221 00:10:32,000 --> 00:10:34,000 Now how many times it will get displayed. 222 00:10:34,000 --> 00:10:36,000 You just see this okay. 223 00:10:36,000 --> 00:10:37,000 Only one time. 224 00:10:37,000 --> 00:10:39,000 Because the next time it became one, this count became one. 225 00:10:39,000 --> 00:10:41,000 The one percentile two is not equal to zero. 226 00:10:41,000 --> 00:10:45,000 So it is just going to come outside of the, uh, loop right of this particular loop. 227 00:10:45,000 --> 00:10:48,000 This is just to show you an example over here. 228 00:10:48,000 --> 00:10:50,000 But we will be seeing with more amazing examples. 229 00:10:50,000 --> 00:10:55,000 First of all, let's go ahead and just see the basic syntax of for while. 230 00:10:55,000 --> 00:10:59,000 And now we are going to go ahead with respect to loop control statements okay. 231 00:11:00,000 --> 00:11:02,000 Loop control statements. 232 00:11:03,000 --> 00:11:05,000 You'll be seeing that, uh. 233 00:11:05,000 --> 00:11:07,000 Uh, please give more examples. 234 00:11:07,000 --> 00:11:07,000 Don't worry. 235 00:11:07,000 --> 00:11:12,000 After I probably make you understand all these things, then we will be seeing more examples as we go 236 00:11:12,000 --> 00:11:12,000 ahead. 237 00:11:12,000 --> 00:11:12,000 Okay. 238 00:11:12,000 --> 00:11:17,000 Now, uh, with respect to the loop control statement, first of all, we'll discuss about something 239 00:11:17,000 --> 00:11:18,000 called as break. 240 00:11:18,000 --> 00:11:18,000 Okay. 241 00:11:18,000 --> 00:11:23,000 Now, if you really want to understand break, I'll just go ahead and write this definition. 242 00:11:23,000 --> 00:11:29,000 The break statement exist exits the loop. 243 00:11:30,000 --> 00:11:31,000 Permanent. 244 00:11:33,000 --> 00:11:36,000 Uh, exits the loop prematurely. 245 00:11:36,000 --> 00:11:36,000 Okay. 246 00:11:36,000 --> 00:11:38,000 What does this basically mean? 247 00:11:38,000 --> 00:11:39,000 I will just make you understand. 248 00:11:39,000 --> 00:11:43,000 Okay, let's say I want to write a break statement. 249 00:11:43,000 --> 00:11:45,000 Now, how do I write a break statement? 250 00:11:46,000 --> 00:11:50,000 So first of all, let's say I am going to run for I in range. 251 00:11:50,000 --> 00:11:51,000 Okay. 252 00:11:51,000 --> 00:11:54,000 Please make sure that you understand the syntax for I in range. 253 00:11:54,000 --> 00:11:56,000 Range of the collection. 254 00:11:56,000 --> 00:11:57,000 This is nothing, but this is collection. 255 00:11:57,000 --> 00:11:58,000 It can be a list. 256 00:11:58,000 --> 00:11:59,000 It can be a dictionary. 257 00:11:59,000 --> 00:12:00,000 It can be range. 258 00:12:00,000 --> 00:12:00,000 It can be string. 259 00:12:00,000 --> 00:12:01,000 Anything. 260 00:12:01,000 --> 00:12:01,000 It can be. 261 00:12:01,000 --> 00:12:03,000 And let's say I'm writing ten. 262 00:12:03,000 --> 00:12:06,000 So ten basically means it is going to iterate from 0 to 1. 263 00:12:06,000 --> 00:12:06,000 Okay. 264 00:12:07,000 --> 00:12:12,000 For one of the condition I'll say if I is double equal to five okay. 265 00:12:12,000 --> 00:12:19,000 If this I is equal to five, I don't want to probably or I want to come outside this particular loop 266 00:12:19,000 --> 00:12:19,000 okay. 267 00:12:19,000 --> 00:12:22,000 I want to come outside this entire for loop. 268 00:12:22,000 --> 00:12:24,000 So I will go ahead and just write break okay. 269 00:12:25,000 --> 00:12:27,000 And once we probably write break okay. 270 00:12:27,000 --> 00:12:32,000 It is probably going to come outside of this particular for loop itself right now. 271 00:12:32,000 --> 00:12:33,000 One more thing. 272 00:12:33,000 --> 00:12:36,000 If I is not equal to five at that time, we just need to print I. 273 00:12:36,000 --> 00:12:36,000 Okay. 274 00:12:36,000 --> 00:12:41,000 So now see what is this entire code that I have actually written for I in range of ten. 275 00:12:41,000 --> 00:12:46,000 If I is double equal to five, I am saying only when I is equal to five do. 276 00:12:46,000 --> 00:12:49,000 The break statement comes outside of this particular for loop. 277 00:12:49,000 --> 00:12:52,000 When I is not equal to five, you just need to keep on printing the numbers. 278 00:12:52,000 --> 00:12:57,000 Okay, so now if I go ahead and execute it here, you'll be able to see 012345. 279 00:12:57,000 --> 00:13:02,000 Then when five came automatically we came outside of this particular for loop Okay. 280 00:13:02,000 --> 00:13:05,000 And then after that nothing is getting printed. 281 00:13:05,000 --> 00:13:09,000 So we are exiting this particular loop permanently. 282 00:13:09,000 --> 00:13:10,000 Okay. 283 00:13:10,000 --> 00:13:12,000 Permanently with the help of break uh, over here. 284 00:13:13,000 --> 00:13:18,000 But this break will only get applied on any statement on any condition as such. 285 00:13:18,000 --> 00:13:18,000 Right. 286 00:13:18,000 --> 00:13:22,000 So that is why we are specifically using this break statement. 287 00:13:22,000 --> 00:13:22,000 Okay. 288 00:13:23,000 --> 00:13:25,000 Uh, this is one of the good examples. 289 00:13:25,000 --> 00:13:30,000 Uh, again, uh, now, with respect to the another loop control statement, we also have something 290 00:13:30,000 --> 00:13:31,000 called as continue. 291 00:13:32,000 --> 00:13:32,000 Okay. 292 00:13:32,000 --> 00:13:35,000 So now we will go ahead and write continue. 293 00:13:35,000 --> 00:13:37,000 Now what exactly continue is okay. 294 00:13:37,000 --> 00:13:43,000 And you also need to know this if I really want to define continue okay. 295 00:13:43,000 --> 00:13:48,000 Continue statement skips the current iteration and continues with the next okay. 296 00:13:48,000 --> 00:13:52,000 So that basically means let's say I'm going to write for I in range okay. 297 00:13:52,000 --> 00:13:55,000 For I in range for I in range. 298 00:13:55,000 --> 00:13:58,000 And let's say I write some elements over here. 299 00:13:58,000 --> 00:13:59,000 Ten okay. 300 00:13:59,000 --> 00:14:06,000 And now if I go ahead and write if I modulus two write is double equal to zero okay. 301 00:14:06,000 --> 00:14:10,000 And this condition is basically just to check whether the number is even or not. 302 00:14:10,000 --> 00:14:15,000 If the number is even, let's say that I will go ahead and write continue okay. 303 00:14:15,000 --> 00:14:17,000 I will just go ahead and write continue. 304 00:14:17,000 --> 00:14:22,000 And then I will just go over here print I. 305 00:14:22,000 --> 00:14:22,000 Okay. 306 00:14:23,000 --> 00:14:28,000 Now, in short, if I really want to make you understand, this is just like displaying all the odd 307 00:14:28,000 --> 00:14:31,000 numbers between 0 to 10, right? 308 00:14:31,000 --> 00:14:33,000 Do you agree with me or not? 309 00:14:33,000 --> 00:14:35,000 See what I'm doing over here for I in range of ten. 310 00:14:35,000 --> 00:14:40,000 If I percent, I if I modulus two is equal to zero, that basically means this is an even number. 311 00:14:40,000 --> 00:14:41,000 We are just going to continue. 312 00:14:41,000 --> 00:14:44,000 Otherwise, if it is not, which is an odd number, we are just going to print it. 313 00:14:44,000 --> 00:14:50,000 So if I go ahead and execute this, you'll be able to see that I will only get an odd number 13579 between 314 00:14:50,000 --> 00:14:51,000 0 to 10. 315 00:14:51,000 --> 00:14:51,000 Right. 316 00:14:51,000 --> 00:14:54,000 And that is what is a continue example. 317 00:14:54,000 --> 00:14:55,000 With respect to computing. 318 00:14:55,000 --> 00:14:57,000 We are just we are just skipping the current iteration. 319 00:14:57,000 --> 00:15:00,000 This will just skip it will even not go to the print statement. 320 00:15:00,000 --> 00:15:02,000 It will just go ahead and continue the loop. 321 00:15:02,000 --> 00:15:03,000 Right. 322 00:15:03,000 --> 00:15:06,000 So this is what is the power with respect to the continue statement. 323 00:15:06,000 --> 00:15:12,000 There is also one more amazing flow control that we use that is basically called as pass okay. 324 00:15:12,000 --> 00:15:17,000 And you should know all these things because some or the other way we will be using all these things. 325 00:15:17,000 --> 00:15:17,000 Right. 326 00:15:17,000 --> 00:15:23,000 Uh, further when we'll be seeing multiple example, the pass statement is a null operation and it does 327 00:15:23,000 --> 00:15:24,000 nothing okay. 328 00:15:24,000 --> 00:15:25,000 It does nothing. 329 00:15:25,000 --> 00:15:27,000 Nothing means nothing, right? 330 00:15:27,000 --> 00:15:31,000 It will just say, hey, I don't want to do anything on a specific condition. 331 00:15:31,000 --> 00:15:31,000 Okay? 332 00:15:31,000 --> 00:15:41,000 So now if we go ahead and write for I in range for I in range of five, let's say okay for I in range 333 00:15:41,000 --> 00:15:41,000 of five. 334 00:15:41,000 --> 00:15:44,000 Let's say I'm giving this particular condition okay. 335 00:15:44,000 --> 00:15:52,000 I'm saying hey if I is equal to three, if I is double equal to three okay. 336 00:15:52,000 --> 00:15:54,000 then I'm saying, hey, just pass. 337 00:15:55,000 --> 00:15:55,000 Okay. 338 00:15:55,000 --> 00:15:56,000 Do nothing. 339 00:15:56,000 --> 00:15:56,000 Okay? 340 00:15:56,000 --> 00:15:59,000 I don't want you to do anything over here. 341 00:15:59,000 --> 00:15:59,000 Okay? 342 00:15:59,000 --> 00:16:03,000 And then we are going to print I. 343 00:16:03,000 --> 00:16:03,000 Okay. 344 00:16:03,000 --> 00:16:06,000 Now see what will happen in this particular case. 345 00:16:06,000 --> 00:16:10,000 Whenever I say hey whenever the number is even just skip this for loop. 346 00:16:10,000 --> 00:16:12,000 But here it is saying do nothing. 347 00:16:12,000 --> 00:16:13,000 Just go ahead. 348 00:16:13,000 --> 00:16:13,000 Right. 349 00:16:13,000 --> 00:16:16,000 Just go ahead and skip it right now. 350 00:16:16,000 --> 00:16:18,000 If I go ahead and execute it now, see what is happening. 351 00:16:18,000 --> 00:16:22,000 Zero is getting displayed, one is getting displayed, two is getting displayed. 352 00:16:22,000 --> 00:16:23,000 When I is three. 353 00:16:24,000 --> 00:16:25,000 Again I'm just saying hey, skip it. 354 00:16:25,000 --> 00:16:27,000 So it has just skipped this if loop right. 355 00:16:27,000 --> 00:16:37,000 Or the best way will be to print something like this okay the number is okay I will write number is 356 00:16:38,000 --> 00:16:39,000 over here as I. 357 00:16:39,000 --> 00:16:39,000 Okay. 358 00:16:39,000 --> 00:16:41,000 Now you'll be able to understand this. 359 00:16:41,000 --> 00:16:42,000 Now this pass. 360 00:16:42,000 --> 00:16:43,000 As soon as we do the pass. 361 00:16:43,000 --> 00:16:46,000 Right at that time, what will happen now? 362 00:16:46,000 --> 00:16:49,000 First of all, see, when I is equal to three, it only this will get printed. 363 00:16:49,000 --> 00:16:50,000 And we are just going to skip this okay. 364 00:16:50,000 --> 00:16:52,000 And do nothing as such. 365 00:16:52,000 --> 00:16:54,000 So here you can see 0123. 366 00:16:54,000 --> 00:16:56,000 The number is 334. 367 00:16:56,000 --> 00:16:56,000 Right. 368 00:16:56,000 --> 00:16:58,000 Pass in. 369 00:16:58,000 --> 00:16:59,000 It's just like a null statement. 370 00:16:59,000 --> 00:17:01,000 Suppose I don't have anything to give over here. 371 00:17:01,000 --> 00:17:05,000 I will just remove this and I will just write pass do nothing as such Okay. 372 00:17:05,000 --> 00:17:08,000 So this can also be useful. 373 00:17:08,000 --> 00:17:09,000 And again we'll talk about it. 374 00:17:09,000 --> 00:17:12,000 What exactly will be the use case over here. 375 00:17:12,000 --> 00:17:13,000 Right. 376 00:17:13,000 --> 00:17:19,000 But most of them if I probably consider pass continue or let's say if I'm probably defining an empty 377 00:17:19,000 --> 00:17:20,000 function. 378 00:17:20,000 --> 00:17:25,000 And if I define an empty function and if I internally write, uh, write just pass. 379 00:17:25,000 --> 00:17:27,000 That basically means that the function does nothing. 380 00:17:27,000 --> 00:17:28,000 Okay. 381 00:17:28,000 --> 00:17:32,000 So this is uh, some of the amazing things that have been brought by Python. 382 00:17:32,000 --> 00:17:36,000 Uh, if I talk about break, this will be very handy because on a certain condition we are just going 383 00:17:36,000 --> 00:17:38,000 to break this or come out of this particular loop. 384 00:17:38,000 --> 00:17:39,000 We can use break. 385 00:17:39,000 --> 00:17:41,000 Then we have continue. 386 00:17:41,000 --> 00:17:42,000 Then we have pass. 387 00:17:42,000 --> 00:17:47,000 Right now let's talk about nested loops okay. 388 00:17:47,000 --> 00:17:50,000 So let's talk about nested loops. 389 00:17:51,000 --> 00:17:57,000 Nested loop is nothing but a loop inside a loop, right? 390 00:17:58,000 --> 00:18:05,000 Let's say I will run a loop for I in range three. 391 00:18:05,000 --> 00:18:06,000 Okay. 392 00:18:06,000 --> 00:18:10,000 And let's say for j in range two okay. 393 00:18:10,000 --> 00:18:16,000 Now what I'm doing and let's say I go ahead and print print. 394 00:18:16,000 --> 00:18:21,000 And here uh with respect to the print statement, let me show you how you can use f string also. 395 00:18:21,000 --> 00:18:27,000 So f uh, f string is nothing but here, uh, I'm basically writing it out and here I'll write I is 396 00:18:27,000 --> 00:18:34,000 equal to will will be equal to I and j is equal to it will be equal to j. 397 00:18:34,000 --> 00:18:35,000 Okay. 398 00:18:35,000 --> 00:18:41,000 So whenever we use this f string formatted statement to display the variables we have to use this curly 399 00:18:41,000 --> 00:18:41,000 braces. 400 00:18:41,000 --> 00:18:46,000 And uh, in short, this is just a formatting option of displaying the string. 401 00:18:46,000 --> 00:18:52,000 I can use this particular string together along with, uh, you know, floor braces so that I can display 402 00:18:52,000 --> 00:18:53,000 that particular variable. 403 00:18:53,000 --> 00:18:55,000 Now, what is exactly happening over here? 404 00:18:56,000 --> 00:18:57,000 See, it is very simple. 405 00:18:57,000 --> 00:19:02,000 Uh, over here, you'll be able to see for I in range of three. 406 00:19:02,000 --> 00:19:02,000 Right. 407 00:19:02,000 --> 00:19:05,000 I'm iterating through another range over here. 408 00:19:05,000 --> 00:19:05,000 Another. 409 00:19:05,000 --> 00:19:06,000 Uh iterables. 410 00:19:06,000 --> 00:19:10,000 Over here, Then I'm also running another iteration over here. 411 00:19:10,000 --> 00:19:10,000 Right. 412 00:19:10,000 --> 00:19:12,000 So there are three elements over here. 413 00:19:12,000 --> 00:19:13,000 So first it will run this. 414 00:19:13,000 --> 00:19:15,000 Then it will go inside this. 415 00:19:15,000 --> 00:19:20,000 And it will complete the inner loop right inner inner loop in our in our for loop. 416 00:19:20,000 --> 00:19:21,000 Then it will go to the outside for loop. 417 00:19:21,000 --> 00:19:25,000 So first time when it gets displayed this is going to get executed for the two times. 418 00:19:25,000 --> 00:19:29,000 Then it will going to go and increment the I to two. 419 00:19:29,000 --> 00:19:34,000 Then again it is going to uh run it for two times for this particular loop. 420 00:19:34,000 --> 00:19:35,000 If you don't know. 421 00:19:35,000 --> 00:19:39,000 If you don't understand, see over here, I'll show you with respect to the output. 422 00:19:39,000 --> 00:19:42,000 So here initially you can see when I is zero J is zero. 423 00:19:42,000 --> 00:19:45,000 Because initially when we are running this particular loop. 424 00:19:45,000 --> 00:19:46,000 Right. 425 00:19:46,000 --> 00:19:49,000 And then when we go inside this particular loop J will run for two times. 426 00:19:49,000 --> 00:19:51,000 So j is running for j is equal to zero, j is equal to one. 427 00:19:51,000 --> 00:19:53,000 Then you have I is equal to one. 428 00:19:53,000 --> 00:19:55,000 Then again j is equal to zero, j is equal to one. 429 00:19:55,000 --> 00:19:56,000 Then you have. 430 00:19:56,000 --> 00:19:59,000 When I is incremented to two, j is equal to zero and j is equal to one. 431 00:19:59,000 --> 00:20:02,000 So it is basically going to run with respect to all the inner loops. 432 00:20:02,000 --> 00:20:03,000 Right. 433 00:20:03,000 --> 00:20:07,000 And here this for loop, every time it will be executed based on the number of range that I've actually 434 00:20:07,000 --> 00:20:08,000 given over here. 435 00:20:08,000 --> 00:20:09,000 Right. 436 00:20:09,000 --> 00:20:13,000 Whenever we insert enter the upper for loop itself. 437 00:20:13,000 --> 00:20:13,000 Right. 438 00:20:13,000 --> 00:20:17,000 So this is just an example of uh for loops over here. 439 00:20:17,000 --> 00:20:18,000 Uh, sorry. 440 00:20:18,000 --> 00:20:20,000 Nested loops over here right now. 441 00:20:20,000 --> 00:20:23,000 Let us go ahead and see some examples. 442 00:20:23,000 --> 00:20:23,000 Okay. 443 00:20:23,000 --> 00:20:26,000 And this is where we will practice multiple things. 444 00:20:26,000 --> 00:20:32,000 Uh, the first examples that uh, we are going to do is that, uh, let's say I am going to write over 445 00:20:32,000 --> 00:20:46,000 here, calculate the sum of first n natural numbers using a while loop, using a while and for loop. 446 00:20:46,000 --> 00:20:51,000 Okay, so let me just go ahead and first of all show you with the help of a while loop. 447 00:20:51,000 --> 00:20:51,000 Okay. 448 00:20:51,000 --> 00:20:54,000 So first, uh, we'll see with respect to the while loop. 449 00:20:54,000 --> 00:20:57,000 And then we will go ahead and see with respect to the for loop. 450 00:20:57,000 --> 00:20:58,000 Okay. 451 00:20:58,000 --> 00:21:02,000 What we need to do calculate the sum of first n natural numbers. 452 00:21:02,000 --> 00:21:02,000 Okay. 453 00:21:02,000 --> 00:21:03,000 First n natural numbers. 454 00:21:03,000 --> 00:21:04,000 Very simple. 455 00:21:04,000 --> 00:21:11,000 So now I will just go ahead and say let's uh, say that the number of uh n number, the natural number 456 00:21:11,000 --> 00:21:11,000 is ten. 457 00:21:11,000 --> 00:21:15,000 Then initially I will define my some variable to zero. 458 00:21:15,000 --> 00:21:20,000 This will be my temporary variable because the addition that I'm going to do with respect to all the 459 00:21:20,000 --> 00:21:23,000 natural numbers, I'm going to save it in this particular variable called as sum. 460 00:21:24,000 --> 00:21:28,000 Then I will keep this temporary variable called as count is equal to one. 461 00:21:28,000 --> 00:21:29,000 Okay. 462 00:21:29,000 --> 00:21:31,000 Now let's go ahead okay. 463 00:21:31,000 --> 00:21:39,000 So here I'm going to write while okay count is less than or equal to n right. 464 00:21:39,000 --> 00:21:45,000 Unless until the count is less than or equal to n I'm going to just go ahead and I'm going to use this 465 00:21:45,000 --> 00:21:48,000 sum is equal to sum plus count. 466 00:21:48,000 --> 00:21:49,000 Right. 467 00:21:49,000 --> 00:21:52,000 So what we are doing over here we keep on adding the count right. 468 00:21:52,000 --> 00:21:55,000 Unless and until this is not equal to less than or equal to n. 469 00:21:55,000 --> 00:21:57,000 And after this we will go ahead and write. 470 00:21:57,000 --> 00:22:00,000 Count is equal to count plus one. 471 00:22:00,000 --> 00:22:02,000 We are incrementing the count variable also. 472 00:22:02,000 --> 00:22:10,000 And finally, when this for loop is a while loop is getting completed, I will write some off first 473 00:22:11,000 --> 00:22:14,000 ten natural numbers. 474 00:22:15,000 --> 00:22:21,000 Okay, natural numbers will be equal to nothing, but whatever sum we are probably getting over here, 475 00:22:21,000 --> 00:22:22,000 Right. 476 00:22:22,000 --> 00:22:23,000 Just go through the statements here. 477 00:22:23,000 --> 00:22:27,000 We have initialized how many number of natural numbers we are going to consider. 478 00:22:27,000 --> 00:22:29,000 Initially, the sum is equal to zero, count is equal to one. 479 00:22:29,000 --> 00:22:35,000 Now I'm saying while count is less than or equal to n, I'm going to increment this count continuously 480 00:22:35,000 --> 00:22:40,000 unless and until this gets satisfied then automatically internally we are doing the sum also. 481 00:22:40,000 --> 00:22:41,000 Okay. 482 00:22:41,000 --> 00:22:44,000 So here you can actually see the sum of first n ten. 483 00:22:44,000 --> 00:22:47,000 Natural number is nothing but 55 perfect. 484 00:22:47,000 --> 00:22:53,000 So this is just like one plus two plus three plus four plus five plus six plus seven plus eight plus 485 00:22:53,000 --> 00:22:54,000 nine plus ten. 486 00:22:54,000 --> 00:22:55,000 Right. 487 00:22:55,000 --> 00:22:56,000 Uh, it will not go. 488 00:22:56,000 --> 00:22:56,000 Uh. 489 00:22:56,000 --> 00:22:59,000 Yeah, it will go till ten because we have written less than or equal to n. 490 00:22:59,000 --> 00:23:00,000 Okay. 491 00:23:00,000 --> 00:23:01,000 Perfect. 492 00:23:01,000 --> 00:23:03,000 So this was one of the example. 493 00:23:03,000 --> 00:23:05,000 Uh, let's do it the same thing with the help of for loop. 494 00:23:05,000 --> 00:23:06,000 So I will write. 495 00:23:06,000 --> 00:23:10,000 Uh, so let me just go ahead and define this three variables again. 496 00:23:11,000 --> 00:23:12,000 Okay. 497 00:23:12,000 --> 00:23:17,000 So let's say for I in range. 498 00:23:17,000 --> 00:23:24,000 And here also I can just go ahead and write till 11 because I want to probably do from zero to 0 to 499 00:23:24,000 --> 00:23:24,000 10. 500 00:23:24,000 --> 00:23:25,000 Okay. 501 00:23:25,000 --> 00:23:29,000 And here I'll just go ahead and write sum is equal to sum plus I. 502 00:23:29,000 --> 00:23:30,000 That's it. 503 00:23:30,000 --> 00:23:31,000 Right. 504 00:23:31,000 --> 00:23:33,000 And here I don't even have to write. 505 00:23:33,000 --> 00:23:35,000 This count is equal to one okay. 506 00:23:35,000 --> 00:23:39,000 Because automatically this will get integrated in uh uh incremented. 507 00:23:39,000 --> 00:23:42,000 So here let me just go ahead and print the sum. 508 00:23:42,000 --> 00:23:46,000 And if I go ahead and execute I'm also able to get it 55 okay. 509 00:23:46,000 --> 00:23:53,000 So here I've shown you with the help of both while and for loop how you can calculate the first ten 510 00:23:53,000 --> 00:23:56,000 natural uh numbers sum. 511 00:23:56,000 --> 00:23:57,000 And here you are able to see it. 512 00:23:57,000 --> 00:23:58,000 Okay. 513 00:23:58,000 --> 00:23:59,000 Now, let me do one thing. 514 00:23:59,000 --> 00:24:02,000 Let me show you one more example. 515 00:24:02,000 --> 00:24:02,000 Okay. 516 00:24:02,000 --> 00:24:05,000 Now this time the examples will be. 517 00:24:07,000 --> 00:24:09,000 Talk about the prime numbers. 518 00:24:09,000 --> 00:24:12,000 Or display the prime numbers between 1 and 100. 519 00:24:12,000 --> 00:24:14,000 Now what is prime number? 520 00:24:14,000 --> 00:24:18,000 Prime number are something which is divisible by one or the number itself. 521 00:24:18,000 --> 00:24:19,000 Right now. 522 00:24:19,000 --> 00:24:22,000 Uh, here I'll just go ahead and write it down. 523 00:24:22,000 --> 00:24:24,000 And again for this I will use a for loop. 524 00:24:24,000 --> 00:24:29,000 So I'll write for num in range of one comma 101. 525 00:24:29,000 --> 00:24:29,000 Right. 526 00:24:29,000 --> 00:24:32,000 Because we need the numbers between 1 and 100. 527 00:24:32,000 --> 00:24:33,000 Right. 528 00:24:33,000 --> 00:24:38,000 If uh the first condition will be that I will go ahead and write if num is greater than one. 529 00:24:38,000 --> 00:24:38,000 Right. 530 00:24:38,000 --> 00:24:41,000 Obviously the number has to be greater than one. 531 00:24:41,000 --> 00:24:42,000 So one condition is over here. 532 00:24:42,000 --> 00:24:45,000 We're going to use if nested if nested for loops. 533 00:24:45,000 --> 00:24:45,000 And. 534 00:24:45,000 --> 00:24:50,000 All right please pause the video, try it by yourself and then probably see the solution. 535 00:24:50,000 --> 00:24:51,000 Okay. 536 00:24:51,000 --> 00:24:58,000 Now if this is true then what I'll do for I in range two comma num okay. 537 00:24:58,000 --> 00:25:02,000 Uh, for I in range two comma num. 538 00:25:02,000 --> 00:25:07,000 That basically means from this number from two to this particular number, whichever number we are specifically 539 00:25:07,000 --> 00:25:14,000 discussing or uh from this for loop which number I'm able to increment, I will just go ahead and write 540 00:25:14,000 --> 00:25:15,000 this particular condition. 541 00:25:15,000 --> 00:25:19,000 If num percentile I right. 542 00:25:19,000 --> 00:25:21,000 I is the same number over there. 543 00:25:21,000 --> 00:25:23,000 Right is equal to zero. 544 00:25:23,000 --> 00:25:26,000 Then we are just going to break it okay. 545 00:25:26,000 --> 00:25:31,000 And then we are just going to break and come outside this for loop. 546 00:25:31,000 --> 00:25:35,000 And I'm going to say else print number okay. 547 00:25:35,000 --> 00:25:35,000 Okay. 548 00:25:36,000 --> 00:25:40,000 We just need to print this because if this gets satisfied right. 549 00:25:40,000 --> 00:25:44,000 This is basically indicating that, hey I've got a prime number. 550 00:25:44,000 --> 00:25:44,000 Right. 551 00:25:44,000 --> 00:25:46,000 And then it is just going to display the prime number. 552 00:25:46,000 --> 00:25:49,000 So again I'm repeating first of all I'm going to check a condition. 553 00:25:49,000 --> 00:25:55,000 If number is greater than one then we are going to write for I in range of two comma num okay two comma 554 00:25:55,000 --> 00:25:55,000 num. 555 00:25:55,000 --> 00:26:00,000 So we are incrementing the uh so so we are running through this particular two comma num whatever num 556 00:26:00,000 --> 00:26:00,000 is there. 557 00:26:00,000 --> 00:26:03,000 Let's say the num is uh three. 558 00:26:03,000 --> 00:26:05,000 So two comma three for range in two comma three. 559 00:26:05,000 --> 00:26:09,000 Then we can go ahead and write three percentile two is double equal to zero. 560 00:26:09,000 --> 00:26:11,000 The answer is no right. 561 00:26:11,000 --> 00:26:14,000 If it is no we are just going to go ahead and display this number. 562 00:26:14,000 --> 00:26:14,000 Right. 563 00:26:14,000 --> 00:26:19,000 And if it breaks it is just going to go outside this particular for loop okay. 564 00:26:19,000 --> 00:26:23,000 So that basically means if this condition is becoming true right. 565 00:26:23,000 --> 00:26:26,000 That basically means it is not a prime number. 566 00:26:26,000 --> 00:26:29,000 Otherwise we are just going to display the number in the else block. 567 00:26:29,000 --> 00:26:30,000 Okay. 568 00:26:30,000 --> 00:26:35,000 And one more thing about for loop is that along with the for loop also you can write else block right 569 00:26:35,000 --> 00:26:41,000 else block if something uh you don't want to execute it, but you want to execute compulsory at the 570 00:26:41,000 --> 00:26:42,000 end of the for loop. 571 00:26:42,000 --> 00:26:45,000 So you can also use this else block okay. 572 00:26:45,000 --> 00:26:47,000 So once I execute this here you'll be able to see two three. 573 00:26:47,000 --> 00:26:50,000 So two is a prime number three is a prime number five. 574 00:26:50,000 --> 00:26:54,000 Seven is a prime number 1113, 17, 19, 23, 29. 575 00:26:54,000 --> 00:26:55,000 All these are prime numbers. 576 00:26:55,000 --> 00:26:57,000 You can probably go ahead and check it out okay. 577 00:26:58,000 --> 00:27:02,000 Uh these are like numbers which are only divisible by one or the number itself. 578 00:27:02,000 --> 00:27:02,000 Right. 579 00:27:02,000 --> 00:27:04,000 So here you can actually see the example. 580 00:27:04,000 --> 00:27:04,000 Okay. 581 00:27:05,000 --> 00:27:13,000 Now some more uh, uh examples that you will be seeing as we go ahead where we'll be using when we learn 582 00:27:13,000 --> 00:27:17,000 more about, uh, different, different data structures like lists and dictionary. 583 00:27:17,000 --> 00:27:22,000 But at the end, uh, conclusion that I really want to give after every lesson. 584 00:27:22,000 --> 00:27:22,000 Right. 585 00:27:22,000 --> 00:27:25,000 And let me make a markdown cell over here. 586 00:27:25,000 --> 00:27:26,000 Okay. 587 00:27:27,000 --> 00:27:30,000 So conclusion is that loops are really powerful. 588 00:27:31,000 --> 00:27:31,000 Okay. 589 00:27:31,000 --> 00:27:35,000 Loops are definitely very, very powerful okay. 590 00:27:36,000 --> 00:27:41,000 Um, in Python that allows you to execute block of code multiple times by understanding, using for 591 00:27:41,000 --> 00:27:44,000 and while loops along with the loop control statement like break, continue, and pass. 592 00:27:44,000 --> 00:27:49,000 You can handle a wide range of programming tasks efficiently, and you'll be seeing that when we will 593 00:27:49,000 --> 00:27:51,000 be discussing about more examples. 594 00:27:51,000 --> 00:27:56,000 But I really want to keep the video between 20 to 25 minutes, where I show you multiple examples where 595 00:27:56,000 --> 00:27:59,000 I write each line of code in front of you so that you'll also be able to understand. 596 00:27:59,000 --> 00:28:01,000 So yes, this was it from my side. 597 00:28:01,000 --> 00:28:02,000 I'll see you all in the next video. 598 00:28:02,000 --> 00:28:02,000 Thank you.
