1、# 定义一个函数def say_good(): print('光芒万丈')
2、# 定义一个简单装饰器def say_name(fn): def tmp(): print('简单装饰器') fn() return tmp
3、# 使用装饰器say_good = say_name(say_good)print(say_good)say_good()
4、print('****原始函数带参数的装饰器*****')def add_fn(a, b, c): print(a+b+c)
5、def say_add(fn): def tmp(*args, **kwargs): print('呵呵呵') fn(*args, **kwargs) return tmpadd_fn = say_add(add_fn)add_fn(3, 6, 8)
6、print('*****原始函数带参数和返回值******')def love(a, b): return a * b
7、def say_love(fn): def tmp(*args, **kwargs): print(666) return fn(*args, **kwargs) return tmplove = say_love(love)a = love(3, 6)print(a)
