class Vehicle(): 
    def is_movable(self): return True

class Car(Vehicle):
    def __init__(self, color): self.color = color
    def has_wheels(self): return True

class CrashedCar(Car): 
    # overloading the grandparent 'is_movable' method
    def is_movable(self): return False



my_car = CrashedCar('silvergray')
my_car.has_wheels()
my_car.is_movable()
