class ArmDog(Dog):

    def work(self):

class DrugDog(Dog):

    def work(self):

class Person:

        self.name = name

    def work_with_dog(self, dog):

        print(f'{self.name}于狗合作完成：', end='')

        dog.work()

if __name__ == '__main__':

    dog = Dog()

    arm = ArmDog()

    drug = DrugDog()
