如何定义需要来自不同类的属性的方法？

class Engine:
    def start(self):
        print("Engine started")

class Car:
    def __init__(self):
        self.engine = Engine()

    def start_car(self):
        self.engine.start()
        print("Car started")

car = Car()
car.start_car()

class Vehicle:
    def start(self):
        print("Vehicle started")

class Car(Vehicle):
    def start_car(self):
        super().start()
        print("Car started")

car = Car()
car.start_car()

from abc import ABC, abstractmethod

class Startable(ABC):
    @abstractmethod
    def start(self):
        pass

class Engine(Startable):
    def start(self):
        print("Engine started")

class Car(Startable):
    def __init__(self):
        self.engine = Engine()

    def start_car(self):
        self.engine.start()
        print("Car started")

car = Car()
car.start_car()
