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
