设计模式（生成器）/属性错误

Question

我想使用builder和prototype模式创建简单的应用程序来构建不同的房屋

（1）修改程序时，我将nameself._builder.name()属性添加到create_house方法中，该方法为我们设置房子的名称。 但是，意外地得到一个错误：AttributeError: 'House1' object has no attribute 'name。我不知道为什么会发生这种情况，因为我认为我已经正确地定义了一切

    class Director():
    def __init__(self, builder):
        self._builder = builder

    def create_house(self):
        self._builder.name()
        self._builder.create_new_house()
        self._builder.add_basement()
        self._builder.add_rooms()
        self._builder.add_roof()

    def get_house(self):
        return self._builder.house


class Builder():

    def __init__(self):
        self.house = None

    def create_new_house(self):
        self.house = House()


class House1(Builder):
    def add_name(self):
        self.house.name = 'house1'

    def add_basement(self):
        self.house.basement = 'with basement'

    def add_roof(self):
        self.house.roof = 'wood roof'

    def add_rooms(self):
        self.house.rooms = 3


class House2(Builder):
    def add_name(self):
        self.house.name = 'house2'

    def add_basement(self):
        self.house.basement = 'no basement'

    def add_roof(self):
        self.house.roof = 'brick roof'

    def add_rooms(self):
        self.house.rooms = 5

class House():

    def __init__(self):
        self.name = None
        self.basement = None
        self.roof = None
        self.rooms = None

    def __str__(self):
        return 'Building: {} {}, {}, and {} room'.format(self.name, self.basement,
                                                           self.roof, self.rooms)


builder = WoodHouse()
director = Director(builder)
director.create_house()
house = director.get_house()
print(house)

(二) 顺便说一句，我会问我是否可以改进（少写）称“建造”房子的过程。 我的意思是这个代码，如果我创建了，例如，3个这样的房子，我必须重复它，然而，这是非常不可读和不方便的

builder = WoodHouse()
    director = Director(builder)
    director.create_house()
    house = director.get_house()
    print(house)

Answer 1

只用于循环

for builder in [WoodHouse(), BrickHouse()]:
    director = Director(builder)
    director.create_house()
    house = director.get_house()
    print(house)
