装饰器它不是一个新的知识点，它是有之前我们学习的名称空间、函数嵌套、闭包函数等知识点汇总而来器：工具装饰：为其他事物添加功能装饰器：不修该装饰的源代码的情况下，不改变源代码的调用的前提下，对装饰对象进行功能的增加。核心思想开放封闭原则：开发：对扩展功能的开放，在源代码不改变的情况下，进行功能的添加封闭：源代码是封闭的

import time#内置时间模块def inside(group,s):    print("欢迎来到英雄联盟")    print(f"你所在的是{group}方阵营")    print(f"敌军还要{s}秒到达战场")    time.sleep(s)#设置时间间隔    print("全军出击")inside("红色",30)#tine.time()时间搓从1970年开始方案1#没有修改调用方式，倒是修改了源代码import time#内置时间模块def inside(group,s):    stm_time=time.time()    print("欢迎来到英雄联盟")    print(f"你所在的是{group}方阵营")    print(f"敌军还要{s}秒到达战场")    time.sleep(s)    print("全军出击")    end_time=time.time()    print(end_time-stm_time)inside("红色",30)

方案二代码冗余import timedef inside(group,s):    print("欢迎来到英雄联盟")    print(f"你所在的是{group}方阵营")    print(f"敌军还要{s}秒到达战场")    time.sleep(s)    print("全军出击")   stm_time=time.time()inside("红色",30)end_time=time.time()print(end_time - stm_time)

方案三调用方式被修改import timedef inside(group,s):    print("欢迎来到英雄联盟")    print(f"你所在的是{group}方阵营")    print(f"敌军还要{s}秒到达战场")    time.sleep(s)    print("全军出击")def worap():    stm_time=time.time()    inside("红色",30)    end_time=time.time()    print(end_time - stm_time)worap()

方案四import timedef inside(group,s):    print("欢迎来到英雄联盟")    print(f"你所在的是{group}方阵营")    print(f"敌军还要{s}秒到达战场")    time.sleep(s)    print("全军出击")def worap(*args,**kwargs):    stm_time=time.time()    inside(*args,**kwargs)    end_time=time.time()    print(end_time - stm_time)worap("蓝色",30)

方案五import timedef inside(group,s):    print("欢迎来到英雄联盟")    print(f"你所在的是{group}方阵营")    print(f"敌军还要{s}秒到达战场")    time.sleep(s)    print("全军出击")def  ouct(func):    # func=inside    def worap(*args,**kwargs):        stm_time=time.time()        func(*args,**kwargs)        end_time=time.time()        print(end_time - stm_time)    return worapres=ouct(inside)res("蓝色",10)

方案六import timedef inside(group,s):    print("欢迎来到英雄联盟")    print(f"你所在的是{group}方阵营")    print(f"敌军还要{s}秒到达战场")    time.sleep(s)    print("全军出击")def  ouct(func):    # func=inside    def worap(*args,**kwargs):        stm_time=time.time()        func(*args,**kwargs)        end_time=time.time()        print(end_time - stm_time)    return worapinside=ouct(inside)inside("蓝色",10)

方案七添加一个充电功能import timedef inside(group,s):    print("欢迎来到英雄联盟")    print(f"你所在的是{group}方阵营")    print(f"敌军还要{s}秒到达战场")    time.sleep(s)    print("全军出击")def recharn(num):    for i in range(num,101):        time.sleep(0.05)        print(f"\r当前电量{"‖"*i}{i}%",end="")    print("电量已充满。")def  ouct(func):    # func=inside    def worap(*args,**kwargs):        stm_time=time.time()        func(*args,**kwargs)        end_time=time.time()        print(end_time - stm_time)    return worapinside=ouct(inside)inside("蓝色",10)recharn=ouct(recharn)recharn(20)

方案八import timedef inside(group,s):    print("欢迎来到英雄联盟")    print(f"你所在的是{group}方阵营")    print(f"敌军还要{s}秒到达战场")    time.sleep(s)    print("全军出击")def recharn(num):    for i in range(num,101):        time.sleep(0.05)        print(f"\r当前电量{"‖"*i}{i}%",end="")    print("电量已充满。")def  ouct(func):    # func=inside    def worap(*args,**kwargs):        stm_time=time.time()        res=func(*args,**kwargs)        end_time=time.time()        print(end_time - stm_time)        return res    return woraprecharn=ouct(recharn)recharn(20)

方案九import timedef  ouct(func):    # func=inside    def worap(*args,**kwargs):        stm_time=time.time()        res=func(*args,**kwargs)        end_time=time.time()        print(end_time - stm_time)        return res    return worap@ouctdef inside(group,s):    print("欢迎来到英雄联盟")    print(f"你所在的是{group}方阵营")    print(f"敌军还要{s}秒到达战场")    time.sleep(s)    print("全军出击")@ouctdef recharn(num):    for i in range(num,101):        time.sleep(0.05)        print(f"\r当前电量{"‖"*i}{i}%",end="")    print("电量已充满。")recharn(20)inside("红色",10)
