WEBVTT 00:01.080 --> 00:06.400 We have another important thing in Python that is called casting. 00:06.560 --> 00:07.520 What is casting? 00:07.880 --> 00:10.360 Casting is changing one type to another type. 00:10.400 --> 00:12.320 For example, we have integer. 00:12.600 --> 00:13.880 I want to change it to string. 00:14.040 --> 00:14.720 Okay. 00:14.760 --> 00:17.160 Or I have integer I want to change it to float. 00:17.200 --> 00:19.040 I have float I want to change it to integer. 00:19.560 --> 00:20.920 How can I do this. 00:21.120 --> 00:21.760 Okay. 00:21.800 --> 00:25.560 Let me come right here and create a new file. 00:25.600 --> 00:28.320 Let's name it cast.py. 00:28.360 --> 00:28.760 Okay. 00:29.360 --> 00:40.120 So for doing that we use those functions like int is changing anything to integer like float is changing 00:40.120 --> 00:42.920 anything to float like str method. 00:43.000 --> 00:48.200 It will change anything to any number to string or any string to string okay. 00:49.360 --> 00:49.800 Let's see. 00:49.800 --> 00:53.000 We have x is equal to 12. 00:53.040 --> 00:55.840 Now let's print type of this okay. 00:56.360 --> 00:57.880 Type of x. 00:58.440 --> 01:01.360 Save it and come here. 01:01.360 --> 01:04.920 Use clear and use Python. 01:04.920 --> 01:07.000 cast.py hit enter. 01:07.000 --> 01:08.680 You see it is integer right now. 01:09.440 --> 01:17.310 And now I am going to use x is equal to is to r and then x. 01:17.590 --> 01:17.990 Okay. 01:18.550 --> 01:20.790 It is one way that you can change it. 01:21.310 --> 01:21.550 Okay. 01:21.550 --> 01:23.190 You may ask what is this thing. 01:24.150 --> 01:28.950 Or if there's a little complex for you I can use it another way too. 01:28.990 --> 01:29.950 Okay. 01:29.950 --> 01:34.030 Now I can give instead of x here 12. 01:34.070 --> 01:35.270 That is also the same. 01:35.590 --> 01:38.590 Or I can give x which has a value. 01:38.630 --> 01:39.870 Value is 12. 01:39.910 --> 01:44.710 Again I will just change the type and again store it into the x variable. 01:44.710 --> 01:47.350 And here I'm printing type of the x. 01:47.870 --> 01:48.350 Now. 01:51.590 --> 01:53.070 Here let's see. 01:54.310 --> 01:57.350 Okay now you see it is giving me store y. 01:57.870 --> 02:00.070 As you see right now we have a number here. 02:00.070 --> 02:03.870 But why it is giving me store is not a string. 02:04.870 --> 02:05.590 Come on. 02:05.630 --> 02:10.470 Of course it is a string because we use str method right here. 02:10.590 --> 02:14.510 Okay, now it is casted or it is changed. 02:14.550 --> 02:18.070 Type of this change to string okay. 02:18.110 --> 02:22.430 We can use this kind of thing in a lot of places okay. 02:22.430 --> 02:26.180 Or I have name which is equal to name add. 02:26.460 --> 02:32.220 And now if I print type of this which is. 02:34.820 --> 02:35.700 Name okay. 02:38.220 --> 02:40.620 And you see it is giving me a string. 02:41.220 --> 02:44.540 And what if I change the type of this. 02:44.980 --> 02:47.860 How can I use str? 02:48.420 --> 02:49.660 Or of course it is str. 02:49.660 --> 02:51.020 I want to change it to integer. 02:51.260 --> 02:51.740 Let's see. 02:51.860 --> 02:53.460 Is it possible or not? 02:56.220 --> 02:56.780 Okay. 02:58.900 --> 03:04.180 No, it is not invalid literal for integer with base ten okay. 03:04.460 --> 03:08.900 You cannot change a string to an integer okay. 03:08.940 --> 03:10.580 It's not possible. 03:10.700 --> 03:12.180 So never try to use it. 03:12.220 --> 03:12.380 Okay. 03:12.380 --> 03:17.940 You cannot change string to a number, but you can change a number to a string. 03:17.980 --> 03:20.940 Okay so let's remove this. 03:22.700 --> 03:25.220 Okay I can save it I can execute this. 03:26.180 --> 03:27.500 It will give me a string. 03:27.540 --> 03:27.940 Okay. 03:28.220 --> 03:29.060 Very good. 03:29.060 --> 03:32.100 You learn how to cast something to another. 03:32.140 --> 03:33.780 Okay I type to another type. 03:34.140 --> 03:36.460 So let's go and see what is next.
