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 , 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 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:
