Python 如何将基类的映射方法用于派生类

更干净和solid的方法是使用单独的映射器/工厂.
而且它甚至更合理，因为在您的例子中，您还需要一个从Dict键到各自模型属性名称的可配置映射.

请考虑以下模式:

class CarModel:
    def __init__(self):
        self.__wheel_count: int = 0

    def wheel_count(self, value: int) -> None:
        self.__wheel_count = value

    wheel_count = property(None, wheel_count)

class TruckModel(CarModel):
    def __init__(self):
        super().__init__()
        self.__load_in_kg: int = 0

    def load_in_kg(self, value: int) -> None:
        self.__load_in_kg= value

    load_in_kg = property(None, load_in_kg)


class VehicleFactory:
    """Vehicle base factory"""
    __model__ = None
    __map_keys__ = None

    @classmethod
    def create(cls, data):
        model = cls.__model__()
        for k, attr in cls.__map_keys__.items():
            setattr(model, attr, data[k])
        return model

class CarFactory(VehicleFactory):
    __model__ = CarModel
    __map_keys__ = {'wheelCount': 'wheel_count'}

class TruckFactory(VehicleFactory):
    __model__ = TruckModel
    __map_keys__ = {'wheelCount': 'wheel_count',
                    'loadInKg': 'load_in_kg'}

用途:

car = CarFactory.create({'wheelCount': 4})
print(vars(car))    # {'_CarModel__wheel_count': 4}

truck = TruckFactory.create({'wheelCount': 4, 'loadInKg': 500})
print(vars(truck))  # {'_CarModel__wheel_count': 4, '_TruckModel__load_in_kg': 500}
