Decorator Maker - how to pass arguments to the decorators

decorator_maker.py

# This script will show how a decorator maker works. This is required for understanding how
# we can pass arguments to the decorators

def decorator_maker():
    print 'I make decorators. I get executed only once when you make or create a decorator'

    def my_decorator(func):
	print 'I am a decorator. I get executed only one when you decorate a function'

	def wrapper():
	    print 'I am the wrapper. I am executed everytime you call the decorated function'
	    return func()
	
	print 'As the decorator, I return the wrapper function'
	return wrapper

    print 'As the decorator maker, I return the decorator'
    return my_decorator

# Now we will decorate a function using the decorator maker. We will have to call the decorator
# maker which will return the decorator using which we will decorate the function

@decorator_maker() 
def decorated_function():
    print 'I am the decorated function'

# Now we will call the decorated function twice
decorated_function()
decorated_function()

# As you saw we used the @ syntax with a function call
