def can_play(clock):
    print('最外层函数被调用了，clock = {}'.format(clock))

    def handle_action(fn):
        print('handle_action被调用了')
        def do_action(name,game):
            if clock < 21:
                fn(name,game)
            else:
                print('太晚了，早点睡')
        return do_action
    return handle_action

@can_play(20)  # 装饰器函数带参数
def play_game(name,game):
    print(name + '正在玩' + game)
play_game('张三','王者荣耀')

结果

最外层函数被调用了，clock = 20
handle_action被调用了
张三正在玩王者荣耀
