WEBVTT 00:01.440 --> 00:06.680 If you remember in the previous lecture, I told you in Python we have two kinds of functions. 00:06.680 --> 00:12.480 One of them is the function that already came with Python, and the other one is a function that you 00:12.520 --> 00:14.600 created in the previous lecture. 00:14.600 --> 00:23.360 We learn how to create a function, and now we are going to learn how to use or what are the function 00:23.360 --> 00:24.840 that comes with Python. 00:24.880 --> 00:27.280 Those are called built in function. 00:27.280 --> 00:29.520 That is here okay I created a new file. 00:30.440 --> 00:35.920 Or let's go ask ChatGPT what is a built in function. 00:35.960 --> 00:47.720 Okay here I have the ChatGPT extension and I am going to ask this built in built in function okay in 00:47.720 --> 00:50.880 Python and just hit enter. 00:52.320 --> 00:54.960 Let's see what is it going to give me. 00:57.400 --> 00:57.800 Okay. 00:57.840 --> 01:02.070 Python has many built in Function that provided useful functionality. 01:02.110 --> 01:07.590 Here are some some commonly used built in functions in Python okay. 01:07.630 --> 01:08.670 Print. 01:08.710 --> 01:11.310 Print is used to display output on the console. 01:11.510 --> 01:12.230 Wow. 01:12.270 --> 01:14.350 Of course it gives you an example. 01:14.430 --> 01:19.750 And also we have the Len function that will return the length of an object of course. 01:19.750 --> 01:22.310 And also we have example we have input function. 01:22.430 --> 01:22.870 Very good. 01:22.870 --> 01:25.230 We haven't learned anything about input function. 01:25.270 --> 01:25.830 Okay. 01:25.870 --> 01:26.550 We have integer. 01:26.550 --> 01:27.190 We have float. 01:27.190 --> 01:27.910 We have string. 01:27.950 --> 01:29.550 We learn those all here. 01:29.590 --> 01:30.510 Okay. 01:30.550 --> 01:31.750 And also we have type. 01:31.750 --> 01:32.590 We learn that okay. 01:32.590 --> 01:33.550 You know what is that. 01:33.830 --> 01:34.230 Okay. 01:34.950 --> 01:40.150 And we have some some some function will some some some number. 01:40.190 --> 01:41.030 Okay. 01:41.070 --> 01:47.150 See we have min max and we have the largest example is an example. 01:47.190 --> 01:47.910 Okay. 01:47.950 --> 01:51.830 Sort function ABC return the absolute value of a number. 01:52.070 --> 01:52.390 Okay. 01:52.430 --> 01:55.710 We have example for that as well okay. 01:56.430 --> 02:00.500 These are just a few examples of Python builds in function. 02:00.500 --> 02:07.500 There are many more functions available and you can also create your own function using def keyword. 02:07.540 --> 02:14.220 Okay, you know this one okay, because we already learned that from all this stuff that ChatGPT gives 02:14.220 --> 02:14.500 me. 02:15.180 --> 02:18.460 One of them is very important and that is the input function. 02:18.460 --> 02:19.380 Let's go and use this. 02:19.420 --> 02:19.980 Okay. 02:20.020 --> 02:21.300 What is input function? 02:21.340 --> 02:26.580 Input function will while you're using it it will ask the user to enter something. 02:26.620 --> 02:27.260 Okay. 02:27.300 --> 02:29.140 Now for example we have a name. 02:29.140 --> 02:32.940 It is equal to input okay. 02:32.940 --> 02:34.900 Here let's ask the user okay. 02:34.940 --> 02:36.300 What is your name. 02:38.340 --> 02:38.700 Okay. 02:38.740 --> 02:42.100 It will ask the user that what is your your name. 02:42.260 --> 02:45.300 And then it will open the console for the user. 02:45.300 --> 02:47.980 So user can enter their name okay. 02:48.020 --> 02:49.420 And name will be stored here. 02:49.420 --> 02:53.140 And then we can print a welcome message to the user. 02:53.140 --> 02:57.540 For example let's say Welcome. 02:58.340 --> 03:02.340 And then concatenate this with net. 03:03.060 --> 03:03.780 Save this. 03:03.940 --> 03:06.260 And now let's execute this okay. 03:06.780 --> 03:10.540 Python and built in function hit enter. 03:10.740 --> 03:16.940 It is asking what is your your name okay here just see the console or the terminal. 03:16.980 --> 03:20.860 I'm going to tell my name is name and hit enter. 03:20.900 --> 03:22.900 It's a welcome name okay. 03:23.260 --> 03:25.100 You can enter your own name again. 03:25.100 --> 03:27.420 Let's go this time with John. 03:28.380 --> 03:30.580 And it is telling me that. 03:30.620 --> 03:31.460 Welcome, John. 03:31.780 --> 03:32.260 Okay. 03:32.300 --> 03:35.020 That is how you can use a built in function. 03:35.020 --> 03:39.020 And you see that ChatGPT gives me a lot of examples here. 03:39.140 --> 03:44.620 And also okay, enter your name, float, blah blah blah. 03:45.700 --> 03:51.420 And also you can create a calculator with this input okay. 03:51.460 --> 03:57.370 For example asking the user to enter the first number, enter the second number and then can calculate 03:57.370 --> 03:58.050 those two number. 03:58.050 --> 04:02.770 For example, sum them, multiply them, or divide them by a number and then print the result. 04:02.770 --> 04:05.130 So you will be having a simple calculator. 04:05.490 --> 04:09.730 So thanks for watching and I will see you in the next lecture. 04:09.730 --> 04:17.370 But before seeing that, I have to show you how I installed this ChatGPT came here into this extension. 04:17.370 --> 04:19.410 Search for ChatGPT. 04:19.450 --> 04:26.890 Okay chat GPT and you see that this one okay. 04:26.890 --> 04:34.290 This is an extension, uh, over 295,000 people installed this. 04:34.290 --> 04:36.410 And you can also install this. 04:36.450 --> 04:37.170 It's very good. 04:37.170 --> 04:42.450 It is helping you a lot in any kind of problem that you face. 04:44.770 --> 04:45.610 Okay. 04:45.650 --> 04:53.130 That is how you can use from AI on learning your your things like Python. 04:53.170 --> 04:55.330 So let's go and see what is next.
