题目描述
1、建立如下的类继承结构：
1)定义一个人员类CPeople，其属性（保护类型）有：姓名、性别、年龄；
2)从CPeople类派生出学生类CStudent，添加属性：学号和入学成绩；
3)从CPeople类再派生出教师类CTeacher，添加属性：职务、部门；
4)从CStudent和CTeacher类共同派生出在职研究生类CGradOnWork，添加属性：研究方向、导师；
2、分别定义以上类的构造函数、输出函数print及其他函数（如需要）。
3、在主函数中定义各种类的对象，并测试之。
输入
第一行：姓名性别年龄
第二行：学号成绩
第三行：职务部门
第四行：研究方向导师
输出
第一行：People:
第二行及以后各行：格式见Sample
输入样例1
wang-li m 23 2012100365 92.5 assistant computer robot zhao-jun
输出样例1
People: Name: wang-li Sex: m Age: 23
Student: Name: wang-li Sex: m Age: 23 No.: 2012100365 Score: 92.5
Teacher: Name: wang-li Sex: m Age: 23 Position: assistant Department: computer
GradOnWork: Name: wang-li Sex: m Age: 23 No.: 2012100365 Score: 92.5 Position: assistant Department: computer Direction: robot Tutor: zhao-jun
思路分析
这道题涉及到类的多重继承，CPeople作为基类派生出CStudent和CTeacher，然后由这两个子类共同派生出CGradOnWork类。
Python的多重继承没有那么复杂，它很聪明，不需要虚函数，它自己会知道要调用哪个成员函数。
而且，对于多重继承来说，两个父类具有相同的属性，这个孙类也只会继承一个。
