python3之面向对象实例存家具

#定义一个房子类以及一个家具类，各自定义属性，实现两个类的关联及调用
class Home:
    def __init__(self,area,info,addr):
        self.area = area #面积
        self.info = info #户型
        self.addr = addr #位置
        self.leftarea = area #剩余面积初始值为全面积
        self.add_jiaju = []
    def __str__(self):
        return "房子面积是%s,户型是%s,位置是%s,老杨新增了家具%s,剩余套内面积%s"%(self.area,self.info,self.addr,str(self.add_jiaju),self.leftarea)
    def add_items(self,items):
        # self.leftarea -= items.area
        # self.add_jiaju.append(items.name)
        self.leftarea -= items.get_area()#直接调用其他类属性改为调函数，后期可控制返回值
        self.add_jiaju.append(items.get_name())
