python3实现名片管理系统（控制台版）

本文实例为大家分享了python3实现名片管理系统的具体代码，供大家参考，具体内容如下

系统主要是：1.新增名片 2.显示全部 3.查询名片 0.退出系统

card_main.py

import card_tools
 
while True:
 \"\"\"
  1.新增名片 2.显示全部 3.查询名片 0.退出系统
 \"\"\"
 
 card_tools.show_menu() # 显示系统菜单
 action_str = card_tools.input_deal()
 
 if action_str == 1:
  print(\"您的操作是：%d\" % action_str)
  card_tools.new_card()
  print()
 elif action_str == 2:
  print(\"您的操作是：%d\" % action_str)
  card_tools.show_all()
  print()
 elif action_str == 3:
  print(\"您的操作是：%d\" % action_str)
  card_tools.find_card()
  print()
 elif action_str == 0:
  print(\"退出系统\")
  break
 else:
  print(\"您输入的不正确\")

card_tools.py

#! /usr/bin/python3
