篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了选课系统相关的知识，希望对你有一定的参考价值。
需求：选课系统开发，要求有四种角色:学校、学员、课程、讲师
详细要求:
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
6、创建讲师角色时要关联学校
7、提供两个角色接口
8、为学员、讲师、管理员分别提供用户界面，并提供对应功能：
a 学员视图， 可以注册， 交学费， 选择班级，
b 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
c 管理视图，创建讲师， 创建班级，创建课程
注1：上面的操作产生的数据都通过pickle序列化保存到文件里
注2：此作业必须画流程图，图中标注好不同类或对象之间的调用关系

数据初始化在“初始化.py”中（两个校区，北京：linux、python，上海：go） 程序开始，运行start.py 初始带有一个管理员（账号：admin，密码：123） 数据信息都在db中，登录信息存在login_info，其余信息通过pickle保存在文件中 老师的登陆信息及信息详情由管理员创建
