Python Decorators | Decorators in Python | How to Use it and Why

In this Python Programming Tutorial for Beginners video I am going to show you How to use decorators in Python. Decorators wrap a function and modify its behaviour in some way or the
another, without having to directly change the source code of the function being decorated. this is the simple A guide to Python's function decorators. In this video we will Write a function decorator that can be used to measure the run time of a functions.

thank u sir i got it, you explained very neatly

in the second example (at 11:15 min) wrapper_func(), we are returning a/b and also in divide(), we are returning x/y. what is the point then? Where are we using the divide() func inside the wrapper_func() as in the previous example we are using the func() explicitly.

I prefer c or c++ programming language becose Python despite it´s oriented object programming language, it´s an intepreted language, thus it´s more slow to compile.

I have a question sir, it involves python but not this video... How can I fix an empty terminal and an exited code output?

1 def decorator_divide(func):
2 def wrapper_func(a, b):
3 print('divide', a, 'and', b)
4 if b == 0 :
5 print('not divisible')
6 return
7 return a/b
8 return wrapper_func

9 @decorator_divide
10 def divide(x, y):
11 print('being called')
12 return x/y
13
14 #print(result_divide(15, 3))
15 print(divide(15, 5))


the print statement @line 11 is not getting printed.
