python 装饰器执行顺序的代码示例

def decoratorA(func):
    print(33)

    def wrapperA():
        print("Entering A")
        print(func())
        print("Exiting A")

    print(44)
    return wrapperA


def decoratorB(func):
    print(11)

    def wrapperB():
        print("Entering B")
        func()
        print("Exiting B")

    print(22)
    return wrapperB


@decoratorB
@decoratorA
def my_function():
    print("Inside my_function")
    return 34


# 调用被装饰器包装的函数
my_function()
