Decorator of python

Decorator is basically function enhancer

Metaphor of decorator can be gift wrapper of the gift

Lets consider a simple example

def prettier(func):
    print("Inside prettier")
    def wrapper():
        print("Making pretty")
        func()
    return wrapper

@prettier
def ordinary_gift():
    print("My ordinary gift")

ordinary_gift()

print("Also This will produce same result")

# @prettier is syntactic sugar of following
ordinary_gift = prettier(ordinary_gift)
ordinary_gift()
