python练习---校园管理系统
角色：
学校、学员、课程、讲师
要求：
1、创建北京、上海2所学校（已完成）
2、创建linux、python、go3个课程，linux/python在北京开，go在上海开（已完成）
3、课程包含周期、价格（已完成）
4、班级关联课程、讲师（已完成）
5、创建学员时，选择学校，关联班级（已完成）
6、提供三个角色视图
6.1：学员视图，登录，查看课程，查看班级（已完成）
6.2：讲师视图，讲师可以查看自己教学的班级，课程（已完成）
进阶需求：可管理自己的班级，查看班级学员列表，修改所管理的成绩（未完成）
6.3：管理视图，创建讲师，创建班级，创建课程（已完成）
7、上面的操作产生的数据通过pickle、序列化保持到文件中（已完成）
下面是具体的实现代码：
代码目录主要有：
实现功能： 1、根据登录用户进行判断，如果是学生就进入学生视图，是老师就进入老师视图，是管理员就进入管理员视图 课程中关联学校、讲师等属性； 班级中关联课程、讲师等属性 学生对象关联了学校、班级等属性； 2、学生视图： a：查看课程 b：查看学校 c：查看班级 3、老师视图： a：查看学校 b：查看讲师 c：查看班级 d：查看课程 4、管理员视图： a：创建学校 b：创建课程 c：创建班级 d：创建学员 e：创建讲师 f：查看学校 g：查看讲师 h：查看班级 i：查看课程 j：给课程关联讲师 k：给学员指定班级 目录结构： bin ---> 程序执行的总入口，直接在pycharm或者其他编辑器中执行start.py conf ---> 配置文件目录，settings.py文件中都是一些文件路径信息 core ---> 程序核心目录，里面分别包含了'学校类'，'老师类'，'学生类'，'班级类'，'课程类'，'管理员类'；其中Main.py(程序主要逻辑判断文件)文件中主要是实现登录验证、根据不同登录用户反射到对应的类中 db ---> 信息存储目录，主要记录'学校'、'老师'、'学生'、'班级'、'课程'、'用户账号密码'等信息 log ---> 程序运行中产生的日志信息，主要是记录对程序执行的所有信息 管理员账号密码：admin 123 老师账号密码：goddess 123 学生账号密码：jack 123
