1 00:00:00,070 --> 00:00:00,400 All right. 2 00:00:00,400 --> 00:00:05,400 So how did you get on? Now if you got stuck or you want to see maybe how I did 3 00:00:05,530 --> 00:00:09,160 it, then continue watching and I'll go through the solution with you. 4 00:00:09,820 --> 00:00:13,870 So first things first, head over to the link and fork your own copy. 5 00:00:15,640 --> 00:00:18,730 Once you've done that, we're going to tackle the to-dos one by one 6 00:00:18,730 --> 00:00:20,560 in order. The first one 7 00:00:20,560 --> 00:00:25,560 asks us to randomly choose a word from the word_list and assign it to a variable 8 00:00:27,820 --> 00:00:28,870 called chosen_word. 9 00:00:29,500 --> 00:00:32,890 So in order to randomly get an item out of the list, 10 00:00:33,190 --> 00:00:36,580 we're going to need to import the random module. 11 00:00:37,900 --> 00:00:42,760 And once we've got hold of that, then we can say random.choice 12 00:00:43,030 --> 00:00:45,490 and if we put inside the parentheses 13 00:00:45,790 --> 00:00:48,610 the list that we want to randomly choose from, 14 00:00:48,970 --> 00:00:53,830 then we should be able to get hold of a single item from this list randomly. 15 00:00:54,370 --> 00:00:58,090 And then finally, we're going to assign it to a variable called chosen_word. 16 00:00:58,510 --> 00:01:03,490 So let's call that chosen_word and then set it to equal this result. 17 00:01:04,900 --> 00:01:09,900 So that's to-do 1 completed. The next todo we have to ask the user to guess a 18 00:01:10,060 --> 00:01:15,060 letter and assign their answer to a variable called guess. And finally make that 19 00:01:16,030 --> 00:01:20,650 guess lowercase. In order to ask the user for anything, 20 00:01:20,680 --> 00:01:24,490 we're going to have to create an input. And let's say, 21 00:01:24,550 --> 00:01:26,650 "Guess a letter:" 22 00:01:29,470 --> 00:01:31,690 And then we can assign their answer 23 00:01:31,720 --> 00:01:36,190 which will replace this line of code with a variable called guess. 24 00:01:36,430 --> 00:01:40,210 So we'll just set that equal to guess. And finally, 25 00:01:40,240 --> 00:01:45,240 we're going to make this guess lower case and we do that by writing .lower. 26 00:01:46,840 --> 00:01:51,790 Now step 3 ask us to check if the letter the user guessed, 27 00:01:51,970 --> 00:01:56,970 which is this guess variable, is one of the letters in the chosen_word. 28 00:01:57,550 --> 00:02:02,550 So this randomly chosen word could be any one of these: ardvack, baboon, or camel. 29 00:02:04,210 --> 00:02:08,080 And we have to somehow check if this letter 30 00:02:08,410 --> 00:02:13,410 which is stored inside this variable guess matches any of the letters inside 31 00:02:13,780 --> 00:02:17,890 this list of words. So, as I mentioned as a hint, 32 00:02:18,100 --> 00:02:22,120 you can have a look at this document from Google for education, 33 00:02:22,420 --> 00:02:24,550 which talks about various things in Python. 34 00:02:25,000 --> 00:02:28,690 And the part I wanted to draw your attention to is the for loop 35 00:02:28,720 --> 00:02:33,400 which we covered previously. So we know that we can use the for loop like this 36 00:02:33,700 --> 00:02:38,700 to loop through a particular list and get hold of each of the items in the list, 37 00:02:40,060 --> 00:02:43,150 like this. So in our case, 38 00:02:43,180 --> 00:02:48,180 all we have to do is say for letter in chosen word, 39 00:02:49,000 --> 00:02:54,000 so this is going to go through this chosen word letter by letter 40 00:02:55,390 --> 00:02:57,130 and each time the loop runs, 41 00:02:57,400 --> 00:03:00,460 we'll get hold of one of letters inside the word. 42 00:03:00,850 --> 00:03:05,290 So the first time that letter variable will equal a, the next time 43 00:03:05,320 --> 00:03:08,140 it will be equal to r and so on and so forth. 44 00:03:08,680 --> 00:03:10,900 So now inside our for loop 45 00:03:10,990 --> 00:03:15,990 we can check to see if the letter that we're currently looking at is double 46 00:03:18,370 --> 00:03:23,370 equals to the letter that the user guessed and in this case, 47 00:03:23,530 --> 00:03:25,480 well then that means its a match, right? 48 00:03:25,510 --> 00:03:29,470 So we're going to print either a match or in my case, I'm just going to write, 49 00:03:29,800 --> 00:03:33,850 uh, Right. And else, namely if it doesn't match, 50 00:03:33,910 --> 00:03:37,510 then we're going to print wrong. That's it. 51 00:03:37,570 --> 00:03:40,870 That's all we have to do to complete all three to-dos. 52 00:03:41,380 --> 00:03:43,210 And now if I run this code, 53 00:03:43,330 --> 00:03:47,980 you can see it's going to ask me to guess a letter. So let's put a, 54 00:03:48,640 --> 00:03:51,850 and then it goes through this loop line by line 55 00:03:51,880 --> 00:03:56,740 to check against this letter that I've guessed. So I'm guessing in this case 56 00:03:56,740 --> 00:03:59,230 the chosen word is aardvark. 57 00:03:59,590 --> 00:04:04,420 So when the loop is running through the first letter a and a match, 58 00:04:04,480 --> 00:04:08,740 so it says right. Then the next time it's looking at the letter 59 00:04:08,800 --> 00:04:11,080 r, a and r does not match 60 00:04:11,080 --> 00:04:16,079 so we get wrong and it continues until it finds all the matches and all the ones 61 00:04:16,930 --> 00:04:21,700 that don't match. Now, if you want to check your code against mine, 62 00:04:22,089 --> 00:04:26,890 simply head over to the URL that's listed in the course resources under app 63 00:04:26,890 --> 00:04:29,560 brewery/day-7-Hangman-1-End 64 00:04:30,010 --> 00:04:33,070 and here you'll be able to see all the code that I went through with you just 65 00:04:33,070 --> 00:04:36,430 now. Now, if you had any issues 66 00:04:36,460 --> 00:04:41,260 understanding how the code worked or how to get to the final solution, 67 00:04:41,680 --> 00:04:43,300 and if you're at all confused, 68 00:04:43,390 --> 00:04:48,390 I recommend putting the code through Thonny and just clicking on the debug to go 69 00:04:48,880 --> 00:04:53,290 through each of the steps one by one. So in this line, 70 00:04:53,320 --> 00:04:58,320 we're going to use the random module and get hold of a random item from this 71 00:05:01,360 --> 00:05:02,193 list. 72 00:05:02,260 --> 00:05:07,260 So, in this case, it's picked camel. And now that camel is going to be equal to 73 00:05:08,380 --> 00:05:10,600 the variable chosen_word. 74 00:05:11,260 --> 00:05:15,010 So on the next step we ask the user to guess a letter. 75 00:05:15,640 --> 00:05:17,290 And once we step into that, 76 00:05:17,530 --> 00:05:21,610 it's going to print that out into the debug console. 77 00:05:21,910 --> 00:05:26,910 And if I put a and hit enter, then guess is now equal to a, 78 00:05:30,280 --> 00:05:33,610 and there's our second variable guess, which is equal to a. 79 00:05:34,270 --> 00:05:38,800 Now we fall into our for loop. And if we step into the loop, 80 00:05:39,100 --> 00:05:43,900 then you can see that the chosen_word is going to be replaced with camel and 81 00:05:43,930 --> 00:05:48,930 letter is going to be replaced with each of the letters in the chosen word one 82 00:05:49,060 --> 00:05:52,030 by one. So the first time loop runs, it's going to be c, 83 00:05:52,630 --> 00:05:57,590 and then it checks to see, well, if c is equal to guess, 84 00:05:57,620 --> 00:06:00,890 which is a, does that match? No, it doesn't. 85 00:06:00,890 --> 00:06:05,060 So it jumps to the else part and it prints out wrong. 86 00:06:07,460 --> 00:06:10,340 And then the loop is going to restart from the top 87 00:06:10,400 --> 00:06:13,130 and we're going to go to the next letter in the chosen word, 88 00:06:13,460 --> 00:06:17,480 which is a. Now in this case, the letter is a 89 00:06:17,900 --> 00:06:22,820 and the guest is a and so that should match. And so it should print, 90 00:06:22,940 --> 00:06:23,773 right. 91 00:06:25,160 --> 00:06:29,030 And then it basically steps through all of these again and again 92 00:06:29,090 --> 00:06:33,230 until we get to the end of the word and we get this printed out. 93 00:06:33,800 --> 00:06:38,090 So have a play around with that and the debug console to wrap your head around 94 00:06:38,090 --> 00:06:40,940 it. And once you're confident, you know, what's going on, 95 00:06:41,210 --> 00:06:44,240 then head over to the next lesson and let's complete step 2.
