Python 程序：选课系统
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 ， linuxpy 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 学校视图，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jison序列化保存到文件里
一、需求分析
程序最终目的是展示三个视图，每个视图有自己的功能：
需要定义的类：
二、目录结构
三、程序
