4.7面向对象

# 选课系统项目中涉及到诸多数据与功能，要求引入面向对象的思想对其进行高度整合
# 1、学校数据与功能整合
# 2、课程数据与功能进行整合
# 3、学生数据与功能进行整合
# 4、讲师数据与功能进行整合
# 5、班级数据与功能进行整合
# ps：不会写的同学，可以先用普通的方式，先把数据与功能都给写好，再考虑基于面向对象的思想进行整合

# 数据部分：
#      校区的名字：如"老男孩上海校区"
#      校区的地址：如"上海虹桥"


#      班级名字
#      班级所在校区
#
#      学生的学校
#      学生的姓名
#      学生的年龄
#      学号
#      学生的性别
#
#      课程名字
#      课程周期
#      课程价格
#
#      老师的名字
#      老师的年龄
#      老师的薪资
#      老师的等级
#
#
# 功能部分：
#      校区创建完毕后，可以为每个校区创建班级
#
#      班级创建完毕后，可以为每个班级创建课程
#
#      学生创建完毕后，学生可以选择班级
#
#      老师创建完毕后，可以为学生打分




#该方法会在对象产生之后自动执行，专门为对象进行初始化操作，可以有任意代码，但一定不能返回非None的值
