def debug(func):
def wrapper(word):
print("[DEBUG]: enter {}()".format(func.__name__))
return func(word)
return wrapper
@debug
def say_hello(word):
print("hello!%s"%(word))
say_hello("hahaha")
例子2
def out(func):
def inner(*args,**kwargs):
print("这是装饰器啊")
func(*args,**kwargs)
# def inner(arg1, arg2):
# print("这是装饰器啊")
# func(arg1, arg2)
# return inner()
return inner
@out
def say(name,age):
print("我的名字是%s,我今年%d了"%(name,age))
say("张三",20)
注意这里
# return inner() return inner ,我一开始写成了 return inner(),这样就丢失参数了,会报错,
