In Python, a decorator is a design pattern that allows you to modify the functionality of a function by wrapping it in another function.

The outer function is called the decorator, which takes the original function as an argument and returns a modified version of it.

def make_pretty(func):
    def inner():
        print("I got decorated")
        func()
    return inner
 
@make_pretty
def ordinary():
    print("I am ordinary")
 
ordinary()  
# Output:
# I got decorated
# I am ordinary

Is there a relationship between Python Decorators and the Decorator Design Pattern that I saw in C++?
