8-1 【Python0014】设计高校人员信息包，并完成测试
【题目描述】定义一个人员类People，其属性有：姓名、性别、年龄；基于People实现学生类Student，添加属性：学号、入学时间和入学成绩；基于People实现教师类Teacher，添加属性：职务、部门、工作时间；基于Student实现究生类Graduate，添加属性：研究方向和导师，分别定义其中的构造函数和输出函数。程序中定义各种类的对象，并完成测试。 基于以上类利用接口实现在职研究生类 GradOnWork。
程序中定义各种类的对象，并完成测试。
【练习要求】请给出源代码程序和运行测试结果，源代码程序要求添加必要的注释。
