python-Decorator

 Decorator:

the decorators are used to modify the behavior of function or class. In Decorators, functions are taken as the argument into another function and then called inside the wrapper function.

Example:


def shout(text):
    return text.upper()
 
def greet(func):
    # storing the function in a variable
    greeting = func("Hi, I am created by a function passed as an argument.")
    print (greeting)
 
greet(shout)

Output:

HI, I AM CREATED BY A FUNCTION PASSED AS AN ARGUMENT.
In the above example, the greet function takes another function as a parameter (shout ). The function passed as an argument is then called inside the function greet
