进行python编程：

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。

class People:
    def __init__(self, name, gender, age):
        self.name = name
        self.gender = gender
        self.age = age

    def display_info(self):
        print(f"姓名: {self.name}, 性别: {self.gender}, 年龄: {self.age}")


class Student(People):
    def __init__(self, name, gender, age, student_id, enrollment_date, entrance_score):
        super().__init__(name, gender, age)
        self.student_id = student_id
        self.enrollment_date = enrollment_date
        self.entrance_score = entrance_score

    def display_info(self):
        super().display_info()
        print(f"学号: {self.student_id}, 入学时间: {self.enrollment_date}, 入学成绩: {self.entrance_score}")


class Teacher(People):
    def __init__(self, name, gender, age, position, department, work_years):
        super().__init__(name, gender, age)
        self.position = position
        self.department = department
        self.work_years = work_years

    def display_info(self):
        super().display_info()
        print(f"职务: {self.position}, 部门: {self.department},工作时间: {self.work_years}")


class Graduate(Student):
    def __init__(self, name, gender, age, student_id, enrollment_date, entrance_score, research_area, advisor):
        super().__init__(name, gender, age, student_id, enrollment_date, entrance_score)
        self.research_area = research_area
        self.advisor = advisor

    def display_info(self):
        super().display_info()
        print(f"研究方向: {self.research_area}, 导师: {self.advisor}")


class GradOnWork(Graduate):
    def __init__(self, name, gender, age, student_id, enrollment_date, entrance_score, research_area, advisor, company):
        super().__init__(name, gender, age, student_id, enrollment_date, entrance_score, research_area, advisor)
        self.company = company

def display_info(self):
    super().display_info()
    print(f"Company: {self.company}")
