一、需求
需求:
角色，讲师＼学员， 用户登陆后根据角色不同，能做的事情不同，分别如下
讲师视图：
管理班级，可创建班级，根据学员qq号把学员加入班级
可创建指定班级的上课纪录，注意一节上课纪录对应多条学员的上课纪录， 即每节课都有整班学员上， 为了纪录每位学员的学习成绩，需在创建每节上课纪录是，同时为这个班的每位学员创建一条上课纪录
为学员批改成绩， 一条一条的手动修改成绩
学员视图：
提交作业
查看作业成绩
一个学员可以同时属于多个班级，就像报了Linux的同时也可以报名Python一样， 所以提交作业时需先选择班级，再选择具体上课的节数
附加：学员可以查看自己的班级成绩排名
二、表结构
三、readme
作者:zz 版本: 学员管理系统 版本 v0.1 开发环境: python3.6 程序介绍: 管理界面： 讲师视图 学员视图 创建讲师 创建学员 讲师视图： 显示可管理的班级 创建班级 为学员分配班级 添加课程计划 创建上课记录 修改学员成绩 学员视图： 上传作业 查看作业成绩 查看班级排名：当前班级日排名和总排名
