WEBVTT 00:01.080 --> 00:02.920 Now let's go for the next lecture. 00:02.920 --> 00:06.560 And that is going to be data type in Python. 00:06.680 --> 00:07.040 Okay. 00:07.400 --> 00:09.480 Let's create a new file. 00:09.920 --> 00:12.080 Okay I also can create it like this. 00:12.440 --> 00:18.000 And let's use data data type dot p y. 00:18.440 --> 00:18.800 Okay. 00:19.440 --> 00:26.840 In Python or in a programming language data type is an important concept okay. 00:26.880 --> 00:34.320 Variables can store data of different types and different types can do different things. 00:34.560 --> 00:35.280 Okay. 00:35.320 --> 00:38.760 So let's go and see those all thing. 00:38.800 --> 00:41.680 Okay let me clear this. 00:42.000 --> 00:49.920 And here one of those types are text type okay. 00:49.960 --> 00:54.320 Text type uh is str or string. 00:54.320 --> 00:55.200 We call it a string. 00:55.240 --> 00:55.760 Okay. 00:55.800 --> 00:56.920 It is a text type. 00:57.440 --> 00:57.960 Okay. 00:57.960 --> 01:01.100 So I will tell you later with a little more example. 01:01.100 --> 01:05.140 So the next part or the second one is numeric types. 01:05.420 --> 01:09.060 Numeric types is like integer okay. 01:09.460 --> 01:13.740 Like float like a complex. 01:15.500 --> 01:19.780 And the next part is sequence sequence type. 01:20.060 --> 01:22.500 The sequence type is like list. 01:22.500 --> 01:29.020 And also we have tuple and we have range. 01:29.660 --> 01:34.300 And sorry we have mapping type. 01:34.340 --> 01:37.140 Mapping type is like dictionary okay. 01:37.940 --> 01:41.620 And we have Boolean. 01:42.740 --> 01:45.620 Boolean is like true and false and something like that. 01:46.100 --> 01:48.380 And also we have binary and a lot of things. 01:48.620 --> 01:54.860 And I think right now this is enough for now because through the course we are going to use these things 01:54.900 --> 01:55.340 a lot. 01:55.380 --> 01:56.220 Okay. 01:56.220 --> 02:00.950 So here we have a built in function. 02:01.070 --> 02:02.510 You may ask what is function? 02:02.510 --> 02:05.070 So don't ask it right now because later I will explain it. 02:05.110 --> 02:05.990 What is a function? 02:06.190 --> 02:09.430 Now just listen what I'm saying okay. 02:09.470 --> 02:14.350 We have a built in function that is called pipe okay. 02:14.390 --> 02:20.950 If you give something or name of a variable to this type function, it will print the type of that for 02:20.950 --> 02:21.230 you. 02:21.710 --> 02:23.950 So let's comment this. 02:24.230 --> 02:25.590 Also you may ask what is comment? 02:25.630 --> 02:26.470 Don't be worry. 02:26.510 --> 02:33.510 Comment is something or is is something that is not going to be executed while we are executing, while 02:33.510 --> 02:37.830 we're running the program. 02:37.990 --> 02:41.950 Now let's see here we have x. 02:41.990 --> 02:43.830 It is equal to 12 okay. 02:44.190 --> 02:45.910 Now let's print type of. 02:45.910 --> 02:52.190 This x print is also a built in function okay a function that is already provided with Python. 02:52.830 --> 02:58.350 Now let's use type of this x and save it. 02:59.230 --> 03:00.050 And I'm right here. 03:00.090 --> 03:03.530 Use Python and then data type. 03:03.570 --> 03:03.970 Okay. 03:08.330 --> 03:11.250 We have data type. 03:13.090 --> 03:14.490 Data type. 03:14.530 --> 03:14.970 Okay. 03:16.290 --> 03:20.170 Dot p y and not open file. 03:20.570 --> 03:22.610 File or directory. 03:22.650 --> 03:22.890 Okay. 03:22.890 --> 03:24.930 We are into the Python basics. 03:26.770 --> 03:27.810 Oh my God. 03:27.810 --> 03:31.170 Here is one of one thing that I have to tell you. 03:31.170 --> 03:32.610 And that is this one. 03:32.610 --> 03:32.850 Okay. 03:32.890 --> 03:38.850 While I created this, uh, file that is out of the Python basics and I cannot run it. 03:38.850 --> 03:39.370 Okay. 03:39.410 --> 03:42.170 So let's move it into the file. 03:43.050 --> 03:43.490 Move. 03:43.770 --> 03:44.210 Yes! 03:44.210 --> 03:44.890 Move it. 03:45.010 --> 03:47.290 Now it is here inside the file. 03:47.290 --> 03:50.610 And now if I execute this again, it will run it. 03:50.610 --> 03:51.170 Okay. 03:51.210 --> 03:53.930 Now you see, it's telling me that it is integer. 03:53.970 --> 03:54.370 Okay. 03:54.370 --> 03:55.490 This is integer. 03:56.090 --> 03:57.930 What if I change it to. 03:57.970 --> 03:58.210 Okay. 03:58.210 --> 04:00.100 Let's start with this. 04:00.140 --> 04:01.460 I want to change it to string. 04:01.860 --> 04:08.260 It's going to be like, um, hello world. 04:08.980 --> 04:11.060 Okay, now let's run it. 04:11.180 --> 04:13.140 And you see, it's giving me str. 04:13.180 --> 04:14.340 That means it is string. 04:14.860 --> 04:16.860 And also how about float. 04:17.060 --> 04:18.140 Let's go with float. 04:20.660 --> 04:21.020 Okay. 04:21.020 --> 04:24.540 This is a float type okay. 04:24.580 --> 04:27.220 And also we have complex list dictionary booleans. 04:27.420 --> 04:28.500 Let's go with booleans. 04:28.740 --> 04:29.100 Okay. 04:29.780 --> 04:30.900 Like true. 04:33.540 --> 04:34.020 Okay. 04:35.380 --> 04:40.500 And it's giving me bool means boolean. 04:40.540 --> 04:40.900 Okay. 04:41.180 --> 04:44.220 So here you see what are the data types. 04:44.460 --> 04:46.740 Some of the data types okay. 04:46.780 --> 04:49.820 And we are going to use it a lot through the course. 04:50.060 --> 04:54.220 And you will learn them through the course. 04:54.340 --> 04:55.180 Okay. 04:55.180 --> 04:58.860 So I will see you in the next lecture.
