如下：

main函数主主要使用while和if实现4功能切换，切换的具体操作由cards_tools中的函数执行。不说了直接上代码，代码都比较简单：

（1）cards_main：

* coding : UTF-8 *

"""
File_name : cards_main.py
Author : jack
Date : 2018.7.18
Function : 名片管理系统主程序
"""
import cards_tools

使用while实现窗口的循环使用

while True:
?? cards_tools.cards_dis()
?? cards_input = input("请选择操作功能：")
?? if cards_input in ["1", "2", "3"]:
????? if cards_input == "1":
???????? print("- " 20)
???????? print("您选择输入的操作代码是: 1" )
???????? cards_tools.cards_add()
????? elif cards_input == "2":
???????? print("- " 20)
???????? print("您选择输入的操作代码是: 2" )
???????? cards_tools.cards_show_all()
????? elif cards_input == "3":
???????? print("- " 20)
???????? print("您选择输入的操作代码是: 3" )
???????? cards_tools.cards_requ()
?? elif cards_input == "0":

????? print("即将退出系统......\n" "已退出系统，欢迎您下次【名片管理系统】！")
????? break
?? else:
