Lecture 60: Python has some functions

Nafees AI Lab

Python's any() finds whether any of the items in an iterable is truthy. The function returns True if at least one item in the iterable is True or evaluates to True when cast to a Boolean. Although the same output can be achieved using a loop, this built-in function offers a more readable and efficient solution.

00:00So, in programming language, there is a concept that uses dry.

00:05Dry means do not repeat yourself.

00:13In coding, we are coding so that we don't write a code.

00:18However, if we go to previous example,

00:22in which you have drawn a rectangle,

00:26I will tell you that you will draw a rectangle.

00:30You will execute this code.

00:32You will say that this is a rectangle.

00:35Then you will draw a rectangle.

00:37You will say that this is a rectangle.

00:39Then you will copy it.

00:41Here I will print it.

00:44I will execute it.

00:46But again, now,

00:49you have to breach the programming.

00:52You are repeating your code.

00:55Now, this problem is not only this.

00:59Basically, when you have code,

01:01there is a problem that you have to do.

01:04For example, you have a game.

01:07This game has multiple functions.

01:10Some enemies, heroes, weapons.

01:13These are all things that you will do.

01:16You will have a big problem.

01:18Problem in the sense of confusion.

01:21The best way is that you will make departments.

01:25Let's say a box or a wrap.

01:29This is also a way to encapsulate.

01:32This is also a way to use functions.

01:34This is also a way to use functions.

01:38Function is very easy to define.

01:41This is a function to delete.

01:42And now you will pull teints your section.

01:43You may put Normals.

01:45And then, then,

01:46touch the parenthesis of はい.

01:48эту thing about check the function.

01:50Finance will click to BP定am.

01:52Por I say the functions used function and then,

01:53customize this function will click on functions.

01:55In this case,

01:58In this case,

01:59for example, I animations current.

02:00And vice versa,

02:01in a way I requisite print here.

02:02Now,

02:03I will remove it.

02:04I am going to remove this, because I will remove this, because I will remove this, and here I will execute this.

02:11Do you want to print this? Strange, this is not a print.

02:17Basically, when you can define a function,

02:23then Python what does it mean?

02:36It means that Python has nothing to give you.

02:40The reason is that for any function to execute your code,

02:45you have to call this function.

02:48When I am going to print, I will call this function.

02:53I will call this code, and I will call this code.

02:58When I am self-defined function, I will call this function.

03:03I will call this function.

03:05I will execute this function.

03:08Now it returns x. Excellent.

03:11If I am going to use the parentheses, this is not a function call.

03:16The parentheses and parentheses are the same.

03:20This is a function call.

03:22When we do this work,

03:24it will basically return the code, which is in it.

03:28However, if I remove this code,

03:30and run it, let's see what happens.

03:32Nothing. However,

03:34an interesting thing happened.

03:36If I am going to print it,

03:38then I will execute it.

03:40If I am going to execute it,

03:42then I will show you a bunch of random code.

03:44I will show you a bunch of random code.

03:46Random code show.

03:48Function, fun name, at, blah, blah, blah.

03:50What is this?

03:51What is this?

03:52This is the function name.

03:53This is the memory address.

03:55The function call is not.

03:57If I am going to call this function,

03:59I will remove it.

04:01Then I will return it.

04:04That is the memory address.

04:06Now check the code

04:21You see, function X.

04:26Then we change the example.

04:32I will write a rectangle code.

04:34This is a rectangle code.

04:36I will say that rectangle code

04:39I will draw two times.

04:42Now, two times,

04:44I will add a rectangle code.

04:48Indentation correct.

04:50Indentation correct.

04:52Indentation correct.

04:54And you call the function.

04:56I will execute it.

04:58By the way, I will remove it.

05:00Okay.

05:02I will execute it.

05:04Now, I will call it again.

05:06I will call it again.

05:08I will call it again.

05:10Now, it is in the function.

05:12Now, I will call it again.

05:14And we will be good to go.

05:16As many times.

05:18Okay.

05:20You can call it again.

05:22And it will execute the code that is inside.

05:24Okay.

05:26You can call it again.

05:28As many times as you want.

05:30But in this case,

05:32your code is much cleaner.

05:34And your result is displayed.

05:36Okay.

05:38This is basic definition

05:40and basic functionality.

05:42This is basic definition

05:44and basic functionality.

05:46The function.

05:48The function.

05:50The function.

05:52The function.

05:54The function.

05:56The function.

05:58The function.

06:00The function.

06:02The function.

06:04The function.

06:06The function.

06:07The function.

06:08The function.

06:09The function.

06:10The function.

06:11The function.
