day26练习

类与对象测验 ​ ​ 1、定义学校类，实例化出：北京校区、上海校区两个对象 ​ 校区独有的特征有： ​ 校区名=“xxx” ​ 校区地址={'city':"所在市",'district':'所在的区'} ​ 多们课程名=['xxx','yyy','zzz'] ​ 多个班级名=['xxx','yyy','zzz']

校区可以： ​ 1、创建班级 ​ 2、查看本校区开设的所有班级名 ​ 3、创建课程 ​ 4、查看本校区开设的所有课程名 ​

2、定义出班级类，实例化出两个班级对象 ​ 班级对象独有的特征： ​ 班级名=‘xxx’ ​ 所属校区名=‘xxx’ ​ 多门课程名=['xxx','yyy','zzz'] ​ 多个讲师名=['xxx','xxx','xxx']

班级可以： ​ 1、查看本班所有的课程 ​ 2、查看本班的任课老师姓名

3、定义课程类，实例化出python、linux、go三门课程对象 ​ 课程对象独有的特征： ​ 课程名=‘xxx’ ​ 周期=‘3mons’ ​ 价格=3000

课程对象可以： ​ 1、查看课程的详细信息

 

4、定义学生类，实例化出张铁蛋、王三炮两名学生对象 ​ 学生对象独有的特征： ​ 学号=10 ​ 名字=”xxx“ ​ 班级名=['xxx','yyy'] ​ 分数=33

学生可以： ​ 1、选择班级 ​ 3、注册，将对象序列化到文件

5、定义讲师类，实例化出egon，lqz，alex，wxx四名老师对象 ​ 老师对象独有的特征： ​ 名字=“xxx” ​ 等级=“xxx”、 ​ 老师可以： ​ 1、修改学生的成绩

st1.choose_cls(c1)

结果：
