用Python實現簡單的名片管理系統

標籤：.com   app   ack   刪除使用者   ima   dea   phone   img   dict   

首先建立項目，包含主程式cards_main和工具庫cards_tools：

如下：

main函數主主要使用while和if實現4功能切換，切換的具體操作由cards_tools中的函數執行。不說了直接上代碼，代碼都比較簡單：

（1）cards_main：

import cards_tools

使用while實現視窗的迴圈使用

while True:
?? cards_tools.cards_dis()
?? cards_input = input("請選擇操作功能：")
?? if cards_input in ["1", "2", "3"]:
????? if cards_input == "1":
???????? print("- " 20)
???????? print("您選擇輸入的作業碼是: 1" )
???????? cards_tools.cards_add()
????? elif cards_input == "2":
???????? print("- " 20)

???????? cards_tools.cards_show_all()

顯示菜單

新增名片
