python编写一个两个类

这里提供一种可能的实现方式，包括两个类：Person和Student。Person类包含个人的基本信息，如姓名和年龄；Student类则是Person类的子类，添加了学生的特有信息，如学号和成绩。

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

    def get_name(self):
        return self.name

    def get_age(self):
        return self.age

    def __str__(self):
        return f"Name: {self.name}, Age: {self.age}"


class Student(Person):
    def __init__(self, name, age, student_id, grade):
        super().__init__(name, age)
        self.student_id = student_id
        self.grade = grade

    def get_student_id(self):
        return self.student_id

    def get_grade(self):
        return self.grade

    def __str__(self):
        return f"{super().__str__()}, Student ID: {self.student_id}, Grade: {self.grade}"

使用示例：

person1 = Person("Alice", 25)
print(person1)
print(person1.get_name())
print(person1.get_age())

student1 = Student("Bob", 20, "001", 90)
print(student1)
print(student1.get_student_id())
print(student1.get_grade())
print(student1.get_name())
print(student1.get_age())

输出结果：

Name: Alice, Age: 25
Alice
25
Name: Bob, Age: 20, Student ID: 001, Grade: 90
001
90
Bob
20
