1.2.python相關元件安裝
1.2.1.更新pip
python -m pip install --upgrade pip注意：如果Python環境安裝在C盤，必須用管理員身份開啟終端窗口才能升級pip，以及安裝模組
1.2.2.安裝Colorama模組
安裝：
Python程式向控制檯輸出彩色文字，先要安裝colorama模組
pip install colorama基礎使用：
1.3.專案描述
1.3.1.專案結構描述
專案採用的是DAO設計模式，封裝資料層的呼叫，封裝資料庫的操作，如果後續表格發生變動，只需要修改dao對應的檔案即可，不需要全部修改。
什麼是DAO，說白了就是封裝資料庫操作，連結跳轉了解:https://blog.csdn.net/zxy144/article/details/109279693
- db：存放於資料庫相關的python類，操作資料表的程式碼
- service：業務類程式碼
- 核心程式碼：app.py
