Python 程序：選課系統
角色:學校、學員、課程、講師
要求:
1. 創建北京、上海 2 所學校
2. 創建linux , python , go 3個課程 ， linux\py 在北京開， go 在上海開
3. 課程包含，周期，價格，通過學校創建課程
4. 通過學校創建班級， 班級關聯課程、講師
5. 創建學員時，選擇學校，關聯班級
5. 創建講師角色時要關聯學校，
6. 提供兩個角色接口
6.1 學員視圖， 可以注冊， 交學費， 選擇班級，
6.2 講師視圖， 講師可管理自己的班級， 上課時選擇班級， 查看班級學員列表 ， 修改所管理的學員的成績
6.3 學校視圖，創建講師， 創建班級，創建課程
7. 上面的操作產生的數據都通過jison序列化保存到文件里
一、需求分析
程序最終目的是展示三個視圖，每個視圖有自己的功能：
需要定義的類：
二、目錄結構
三、程序
