给定一个Person 类，创建一个子类，增加一个role 属性。实例化一个子类并调用其get_information 方法

好的，以下是代码实现：

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

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


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

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


employee = Employee("Tom", 25, "Manager")
print(employee.get_information())

输出：

Name: Tom, Age: 25, Role: Manager
