1.2.python相关组件安装
1.2.1.更新pip
python -m pip install --upgrade pip
注意：如果Python环境安装在C盘，必须用管理员身份打开终端窗口才能升级pip，以及安装模块
1.2.2.安装Colorama模块
安装：
Python程序向控制台输出彩色文字，先要安装colorama模块
pip install colorama基础使用：
1.3.项目描述
1.3.1.项目结构描述
项目采用的是DAO设计模式，封装数据层的调用，封装数据库的操作，如果后续表格发生变动，只需要修改dao对应的文件即可，不需要全部修改。
什么是DAO，说白了就是封装数据库操作，链接跳转了解:https://blog.csdn.net/zxy144/article/details/109279693
- db：存放于数据库相关的python类，操作数据表的代码
- service：业务类代码
- 核心代码：app.py
