rem 代碼 card 刪除 import val 字典 fin pytho

首先新建項目，包含主程序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實現窗口的循環使用

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":
