python做名片管理系统_用Python实现简单的名片管理系统

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：

使用while实现窗口的循环使用

cards_tools.cards_dis()

print("- " 20)

print("- " 20)

cards_tools.cards_show_all()

print("- " 20)

print("您选择输入的操作代码是: 3" )

cards_tools.cards_requ()

elif cards_input == "0":
