# 设计一个房子类
class House(object):
    def __init__(self,address, area):
        self.address = address
        self.area = area
        self.free_area = self.area * 0.3
        # 定义一个用来保存家具的容器属性
        self.furniture = []

    # 实现一个添加家具的方法
    def add_furniture(self,fur):
        # 先判断剩余 面积是否够添加 到房中
        if fur.area < self.free_area:
            self.furniture.append(fur)
            self.free_area -= fur.area
            print(f'剩余空间还有 {self.free_area} 平米')
        else:
            print('空间不够，无法添加新家具')

    # 实现显示方法
        def __str__(self):
            s = f'我的大House在{self.address},占地{self.area}平方米 \n'
            if len(self.furniture) == 0:
                s += '还未添加家具 \n'
                return s
            else:
                s += '家具如下： \n'
                for f in self.furniture:
                    s += (str(f) )
            return s


# 测试
home = House('博学家园96号701室', 100)
print(home)

#　添加家具
home.add_furniture(Furniture('双人床',6))
home.add_furniture(Furniture('饭桌',4))
home.add_furniture(Furniture('大衣柜',10))
home.add_furniture(Furniture('书桌',10))
