选课系统项目_python
一、功能简要
基本实现以下功能，但是有部分地方由于时间关系并未写，而且并未做细微的完善，大致功能完成。
角色:学校、学员、课程、讲师
要求:
1. 创建北京、上海 2 所学校
2. 创建linux , python , go 3个课程 ， linux\py 在北京开， go 在上海开
3. 课程包含，周期，价格，通过学校创建课程
4. 通过学校创建班级， 班级关联课程、讲师
5. 创建学员时，选择学校，关联班级
5. 创建讲师角色时要关联学校，
6. 提供两个角色接口
6.1 学员视图， 可以注册， 交学费， 选择班级，
6.2 讲师视图， 讲师可管理自己的班级， 上课时选择班级， 查看班级学员列表 ， 修改所管理的学员的成绩
6.3 管理视图，创建讲师， 创建班级，创建课程
7. 上面的操作产生的数据都通过pickle序列化保存到文件里
二、代码解析
