用Python实现简单的名片管理系统

Posted 2020-12-05

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...... " "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

（2）cards_tools：

显示菜单

新增名片
