首先新建项目，包含主程序cards_main和工具库cards_tools：
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("您选择输入的操作代码是: 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: cards_input = input("输入错误，请重新输入:") cards_tools.cards_dis() #cards_input = input("输入错误，请重新输入:") while True: cards_input = input("输入错误，请重新输入:") cards_tools.cards_dis() if cards_input in ["1", "2", "3", "0"]: if cards_input == "1": print("- " * 20) print("您选择输入的操作代码是: 1") cards_tools.cards_add() break if cards_input == "2": print("- " * 20) print("您选择输入的操作代码是: 2") cards_tools.cards_show_all() break if cards_input == "3": print("- " * 20) print("您选择输入的操作代码是: 3") cards_tools.cards_requ() break else: # #print("返回主菜单") break break （2）cards_tools：
