Python---面向对象---修学校

一、创建北京和成都两个校区：

　　1、创建LinuxPython两个课程

　　2、创建北京校区的Python 3期课程和成都校区的Linux 1期课程

　　3、管理员创建了北京校区的学员小张，并将其分配在了Python 3期

　　4、管理员创建了讲师小周，并将其分配了Python 3期

　　5、讲师小周创建了一条Python 3期的上课记录Day02

　　6、讲师小周为Day02这节课所有的学院批改了作业，小张得了A，小王得了B

　　7、学员小张查看了自己所报的课程

　　8、学员小张在查看了自己在Python3的成绩列表然后退出了

　　9、学院小张给了讲师小周好评
