使用Pyton将MAC地址转换成指定格式

python3.6
pycharm2021.3.3
相关需要转换的文件

a.创建文件夹macchange，将需要转换的文件放入。文件夹的目录应在所需要的运行程序的当前目录下！
b.根据当前的格式选择不同的选项。

主函数部分

import os
import time

import cs
path = os.listdir("macchange")
print(path)
print("1.xx-xx-xx-xx-xx-xx >> xxxx.xxxx.xxxx")
print("2.xxxx-xxxx-xxxx >> xxxx.xxxx.xxxx")
print("3.xx.xx.xx.xx.xx.xx >> xxxx.xxxx.xxxx")
print("please input your chooce:")
key = input()
print(type(key))
while(key not in "123"):
    print("please input key again:")
    key = input()
for i in path:

    newpath = "macchange/"+i
    if key=="1":
        print(i + " start")
        cs.macfun.mac1(newpath)
        print(i + " end")
    if key=="2":
        print(i + " start")
        cs.macfun.mac2(newpath)
        print(i + " end")
    if key=="3":
        print(i + " start")
        cs.macfun.mac3(newpath)
        print(i + " end")
print("please input anykey to exit")
input()
