学习记录:python实现一个简易的校园管理系统7.19

实现一个简易的校园管理系统，使用容器保存学生数据和老师数据。

学员信息有: 姓名， 年龄， 性别，班级，学号
讲师信息有:姓名， 年龄， 性别, 课程， 工号

（可以使用列表嵌套字典的方式保存学生和讲师数据
例：stulist=[{“name”:“zhang”,“age”:18,…},{“name”:“zhang”,“age”:18,…},{“name”:“zhang”,“age”:18,…}]
）

1.程序开启时，提示用户输入用户名密码，如果输入错误，则重新输入，最多不超过3次。
（每一个具体功能用函数单独编写，然后统一调用）

2.输入正确后，显示以下菜单并完善其功能：
显示所有学生信息
显示所有老师信息
学校招生（增加学生信息）
学校招聘讲师（增加老师信息）
学生毕业（根据学号删除学生信息）
讲师离职（根据工号删除老师信息）
根据学号修改学生信息
根据姓名修改讲师信息
退出程序
