python【项目】：选课系统【简易版】
- 功能要求
角色:学校、学员、课程、讲师
要求:
1. 创建学校
2. 创建课程
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 ， 创建学员的成绩
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
8. 增加日志文件，能同时输出到控制台
9. 用户认证采用装饰
10.增加try捕捉错误信息
- 开发环境
- python 3.6.1
- PyCharm 2016.2.3
- 数据流图与业务功能图
- 主程序数据流图
2.业务功能图
- 目录结构
- 程序设计
