car_engine = Engine() car_wheels = Wheels() my_car = Car(car_engine, car_wheels) print(my_car.drive()) # Output: Engine started and Wheels rolling 在这个例子中,Car类通过对象组合包含了Engine和Wheels的功能,而不是通过继承。这使得我们可以更灵活地组合不同的部件,而不受继承层次的限制。 优势...

def stop_engine(self): print(f"{self.make} {self.model} engine stopped.") 在这个例子中 ,Car类有三个属性:make(制造商)、model(型号)和year(年份),以及两个方法:start_engine和stop_engine。类定义完成后,我们可以通过实例化来创建具体的汽车对象: ...
