#多個裝飾器裝飾一個函數def wrapper1(func):
    def inner1():
        print('wrapper1 ,before func')
        ret = func()
        print('wrapper1 ,after func')
        return  ret
    return  inner1
def wrapper2(func):
    def inner2():
        print('wrapper2 ,before func')
        ret = func()
        print('wrapper2 ,after func')
        return  ret
    return  inner2

def wrapper9(func):
    def inner3():
        print('wrapper3 ,before func')
        ret = func()
        print('wrapper3 ,after func')
        print('test 1')
        return  ret
    return  inner3
@wrapper9@wrapper2@wrapper1
def f():
    print('in f')
    return  '哈哈哈'
print(f())
執行結果:

wrapper3 ,before func
wrapper2 ,before func
wrapper1 ,before func
in f
wrapper1 ,after func
wrapper2 ,after func
wrapper3 ,after func
test 1
哈哈哈
