python之路——作业：学生选课系统
一、作业要求：
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 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

三、程序已实现功能
程序实现了以下功能：
1、创建管理员（已有管理员：japhi、alex；密码都是123）
2、管理员创建老师（已有老师：李杰、林海峰、武佩奇）
3、管理员创建班级（已有班级：go1班、python1班、linux1班）
4、管理员创建课程（已有课程：go、python、linux）
5、管理员查看老师、班级、课程信息
6、老师修改学生成绩
7、老师查看班级和学生信息
8、学生注册及缴费（已有学生：alex、张三、李四、王五、赵六）
9、数据序列号保存并读取
四、流程图
五、作业代码
