class MyDecorator:

    def __init__(self,f):

        print("Initializing MyDecorator...")

        self.func = f

    def __call__(self):

        print("Begin :{0}".format(self.func.__name__))

        self.func()

        print("End :{0}".format(self.func.__name__))

def print_hello():

    print("Hello.")

#print_hello = MyDecorator(print_hello)

my_decorator = MyDecorator(print_hello)

#print_hello()

my_decorator()

위와 같이 수정하면 어떨까요?
