WEBVTT 00:02.070 --> 00:04.530 So let's continue working with the tax data. 00:05.250 --> 00:11.620 So in the last video, we have learned how to read this CSC file and how to write into a CSA fight. 00:12.060 --> 00:18.840 But that is all based on all those fancy functions are available inside this Third-Party library pangas, 00:19.380 --> 00:23.480 how they can deal with the inbuilt functions that are available in a patent. 00:23.940 --> 00:29.820 So something like open function or like function, read, function, how we can use it. 00:30.360 --> 00:32.670 And for doing that, we need some fine. 00:33.000 --> 00:39.360 So first to recreate one file and then with the with the help of this building functions available in 00:39.360 --> 00:40.630 a python code. 00:41.580 --> 00:45.180 How we can redefine and how we can write into a file. 00:46.390 --> 00:51.170 So to create the file, we can just simply magically use this Jupiter cell. 00:51.370 --> 00:58.240 There are some magic commands available to do tasks like reading file and writing into files. 00:59.990 --> 01:01.990 So we can use like a double percentage. 01:03.340 --> 01:03.800 Let's see. 01:04.650 --> 01:06.270 All right, fine. 01:08.020 --> 01:10.870 Let me give you the name like this one. 01:11.480 --> 01:12.580 Dee da Dee Dee. 01:14.610 --> 01:15.390 Let me, Lenny. 01:17.520 --> 01:23.400 Hopes it says that the cell body is empty because of the creation of file. 01:23.690 --> 01:25.830 You can go and refresh it. 01:26.340 --> 01:27.040 There is no file. 01:27.240 --> 01:33.150 God created software that you how to write some text because what you are going to write inside this 01:33.150 --> 01:34.380 takes place to undock. 01:34.730 --> 01:35.220 Define. 01:36.440 --> 01:44.210 Let's say will give the contain like, hello, this is Tesfai. 01:45.630 --> 01:53.730 Let's say this is the first line ups and this is the second line. 01:54.630 --> 01:57.990 Let me make it like any flexicurity. 01:59.250 --> 02:02.910 You can see the writing and do a test, one to fight. 02:03.660 --> 02:10.410 You can go to the file explorer and you can see based on that text file got created, Double-Click, 02:10.500 --> 02:11.980 click on it and verified. 02:12.840 --> 02:19.640 And you'd be able to see it's what created and has been written with this text like Miklosi. 02:20.890 --> 02:24.250 Now, suppose in the same file if you want to paint something. 02:25.790 --> 02:29.390 So same magic function you can use, but. 02:30.640 --> 02:32.530 With one argument, let's say hi. 02:33.940 --> 02:36.840 A taste when not the extreme. 02:38.250 --> 02:44.470 So let's say Harry in pain mode. 02:45.580 --> 02:46.030 All right. 02:47.180 --> 02:49.310 So this week, file got created. 02:49.460 --> 02:50.810 And let's just verify. 02:53.600 --> 02:59.550 Swelling in pain more, and you can see there is no sless in that side as appendix, along with the 02:59.550 --> 03:02.750 very last character after the very last character of this fight. 03:03.270 --> 03:03.590 All right. 03:03.900 --> 03:04.530 But that's OK. 03:04.800 --> 03:05.880 Her file got created. 03:06.330 --> 03:07.050 Now we'll see. 03:07.710 --> 03:13.860 With the help of building functions available in a pipe and how we can read this, page one not to define. 03:15.950 --> 03:19.130 And for that, we are going to use these simple open function. 03:20.360 --> 03:23.270 Let me give you taste one. 03:23.980 --> 03:24.960 Not the 60. 03:25.850 --> 03:31.790 And now, along with the file name, there are a number of options are available, like what you are 03:31.790 --> 03:34.880 going to do with Despain, whether you want to read this file. 03:34.990 --> 03:39.320 You know, reading more, writing more or some spending more. 03:39.920 --> 03:41.810 So if you just see the documentation. 03:44.490 --> 03:49.950 The very first place he admits it's what it takes, learning more. 03:50.100 --> 03:51.630 And we are going to read this fine. 03:52.830 --> 03:53.370 Read more. 03:53.550 --> 03:54.530 So let me just skip it. 03:57.240 --> 03:58.630 That will be nothing more. 03:59.430 --> 04:01.440 And let me assign it to some fine point. 04:01.800 --> 04:02.900 A fine object. 04:04.570 --> 04:07.700 Let's see if I tried to display this file object. 04:08.950 --> 04:11.020 It will be a kind of tax. 04:11.140 --> 04:13.150 Are you able to kind of plus. 04:14.640 --> 04:22.350 Now, suppose if you want to read this, fine, you can just simply use that lead function and all the 04:22.350 --> 04:26.870 contents are really well in this file going, that will be read in a one shot. 04:28.090 --> 04:34.780 Suppose if you try to read the same thing again, let's say so, fail to read. 04:37.950 --> 04:39.990 All right, so now you can see what happens. 04:40.380 --> 04:48.270 We got the blank, empty string, so here the file point, that is the very first time pointing to very 04:48.270 --> 04:55.810 first character of this test, went out to define the moment you viewed one moment to apply this real 04:55.830 --> 04:58.050 function on the top of this file object. 04:58.530 --> 05:00.720 It has already reached the end of the file. 05:01.110 --> 05:04.350 Now, after the end of the file, there is no character left. 05:04.620 --> 05:06.390 So there is nothing to read. 05:06.660 --> 05:12.300 So in that case, again, you have to open this file and you have to put this puzzle at a very stark 05:12.600 --> 05:13.120 location. 05:14.810 --> 05:17.560 But there is some other mechanism also, like a. 05:18.440 --> 05:22.810 So you can use like a sick function and make it to zero Lachman's. 05:22.880 --> 05:26.780 Now we are pointing to at the very start of the stream of the fight. 05:27.380 --> 05:34.940 And after that, let's say if you try to read, you will be able to read this whole file. 05:35.550 --> 05:38.160 One second simply of a. 05:41.250 --> 05:47.370 Let's say if you want to make this file or seek at some other location, let's say one. 05:49.660 --> 05:50.020 And. 05:51.510 --> 05:59.820 After that, if you just try to really file Naukri, you can observe that the very first character, 05:59.910 --> 06:07.140 it won't be able to read because now we are seeking from the first position and one is pointing here 06:07.290 --> 06:10.380 to the E, not at the very first character of the. 06:13.070 --> 06:19.640 Now, let me make this stick to those zero and we will see some other matter. 06:20.400 --> 06:22.130 To read the same fine. 06:24.130 --> 06:32.120 So it is not just that we can lead with the help of this read function, but we how like all read lines. 06:32.740 --> 06:35.080 So we'll we only know we have a clue. 06:35.080 --> 06:42.330 Lines are available and all the lines we will get has a very loose inside the list object. 06:43.840 --> 06:51.940 Let me go to the first audition in a sec again, and I will show you how you can understand why I have 06:51.940 --> 06:52.660 to do this. 06:52.840 --> 06:53.650 Seek a deal. 06:53.770 --> 06:58.350 Again and again, because I want to put my cursor at the very first I sent, you know. 06:59.830 --> 07:05.800 So this will every single line and put it in two different different values in less. 07:06.490 --> 07:10.510 But there will be one more function, like a lead line. 07:10.960 --> 07:13.620 Now it just hopes it will be a lead. 07:15.930 --> 07:16.260 Line. 07:17.200 --> 07:23.370 Now, just make sure that this is a lead line, so every single line, it will read it here, it's a 07:23.370 --> 07:24.210 V line. 07:24.300 --> 07:27.120 So one by one line it will really. 07:27.570 --> 07:31.140 So now you can see only first line got read. 07:31.620 --> 07:36.420 If I just execute it again, the second line will read. 07:36.900 --> 07:42.190 So this way, if you want to read this file in some sort of file, one by one, line by line, really, 07:42.420 --> 07:44.040 you can put it in inside for. 07:46.160 --> 07:49.490 And let's say if you try to run it once more. 07:50.690 --> 07:52.730 The moment you leap to the end of the fight. 07:52.820 --> 07:54.270 Let me do it once again. 07:55.700 --> 07:57.340 Whoops, there is nothing left. 07:59.730 --> 08:01.590 So you can make C zero. 08:01.740 --> 08:03.750 And again, you can read every single line. 08:04.870 --> 08:10.960 Now, suppose if you want to check whether Feis position is open or closed. 08:11.250 --> 08:14.080 You can use Leiker is underscore. 08:15.470 --> 08:16.910 Hopes it will be a close. 08:17.960 --> 08:22.010 So as of now, it will be kind of nice because file is not close. 08:22.490 --> 08:25.430 You can explicitly make a file like of close. 08:26.080 --> 08:31.160 Now, once you make the file closed, you just cannot apply any operation afterwards. 08:31.520 --> 08:36.220 And it is always a good practice that you close the file after you do all those operations. 08:36.560 --> 08:43.790 So suppose if I tried to read, you can see what errors will get. 08:44.480 --> 08:49.310 So that will be like how you operation on a closed pipe because file is closed and you are trying to 08:49.310 --> 08:50.510 do those operation. 08:52.890 --> 08:54.890 So here we hold explicitly open the file. 08:55.410 --> 08:58.230 And after doing all those operations, we have to close this fight. 08:58.790 --> 09:00.750 But suppose you don't want to close it. 09:01.770 --> 09:08.940 So that is one method like a you can use a result were available in a fighting and you can use like 09:08.940 --> 09:09.420 open. 09:10.320 --> 09:20.920 Let me use this one, not the extreme inner deal more, let's say, as five. 09:21.390 --> 09:25.100 So despite going to exactly the same as our lead file binder. 09:26.760 --> 09:38.430 And let me bring this file, not, you know, in such a condition, you will be able to see that this 09:38.430 --> 09:38.870 spring. 09:40.420 --> 09:42.420 He's inside this week. 09:43.150 --> 09:44.770 That means everything. 09:46.170 --> 09:53.020 Whatever operation you are being related to fight that is inside the sandbox of, you can see this veto 09:53.120 --> 09:53.450 block. 09:53.790 --> 09:56.270 So you do not need to worry about this closing the fight. 09:56.310 --> 10:02.220 The moment you come out from this V block automatically file closing will be the. 10:05.010 --> 10:12.880 Now, if you observe our original file, this one thing that will be us less than exist, end of the 10:13.050 --> 10:14.160 every single line. 10:14.570 --> 10:16.970 Suppose you want to remove that lesson. 10:17.490 --> 10:21.090 So one by one, while Rudy let me know. 10:21.330 --> 10:23.370 Same thing with this roadblock. 10:24.180 --> 10:30.840 And after reading, it will return a string object so we can apply like hopes it will be a strict. 10:34.280 --> 10:34.490 So. 10:35.060 --> 10:40.890 Anyhow, it is not going to bring that lesson, but obviously you can do more. 10:41.190 --> 10:47.750 All those whitespace character nine such a case when you use the brain function, you won't be able 10:47.750 --> 10:50.590 to get those noticeable difference. 10:51.840 --> 10:56.540 All right, so most live heard that in this video, how to lead the fight in the next video. 10:56.570 --> 10:58.880 We will see how to add lighting to find.
