Python에서 함수 데코레이터를 만들고 연결하는 방법은 무엇입니까?

def make_bold(fn):
    # The new function the decorator returns
    def wrapper():
        # Insertion of some code before and after
        return "<b>" + fn() + "</b>"
    return wrapper

@make_bold
@make_italic
def say():
    return "hello"

@make_bold
@make_italic
def formatted_text(text):
    return text

print(formatted_text("Hello world"))

<b><i>Hello world</i></b>

def a_decorator_passing_arguments(function_to_decorate):
    def a_wrapper_accepting_arguments(arg1, arg2):
        print("I got args! Look: {0}, {1}".format(arg1, arg2))
        function_to_decorate(arg1, arg2)
    return a_wrapper_accepting_arguments

@a_decorator_passing_arguments
def print_full_name(first_name, last_name):
    print("My name is {0} {1}".format(first_name, last_name))

print_full_name("Peter", "Venkman")

I got args! Look: Peter, Venkman
My name is Peter Venkman
