Python 装饰器的嵌套

1. 多层装饰器嵌套

def makeBold(func):
    def wrapper(*args, **kwargs):
        return "<b>" + func() + "<b>"
    return wrapper


def makeItail(func):
    def wrapper(*args, **kwargs):
        return "<i>" + func() + "<i>"
    return wrapper


@makeItail
def test1():
    return "hello world"

@makeBold
def test2():
    return "hello world"

@makeBold
@makeItail
def test3():
    return "hello world"

print(test1())
print(test2())
print(test3())

2. 输出结果
