家具类函数定义
class HouseItem:
def __init__(self,name,area):
self.name = name
self.area = area
def __str__(self):
return "[%s] 占地 %.2f"% (self.name,self.area)
bed = HouseItem("席梦思",4)
chest = HouseItem("衣柜",2)
table = HouseItem("餐桌",1.5)
print(bed)
print(chest)
print(table)

房子类定义
class HouseItem:
def __init__(self,name,area):
self.name = name
self.area = area
def __str__(self):
return "[%s] 占地 %.2f"% (self.name,self.area)
class House:
def __init__(self,house_type,area):
self.house_type = house_type
self.area = area
self.free_area = area
self.itme_list = []
def __str__(self):
return ("户型:%s\n总面积: %.2f [剩余:%.2f]\n 家具:%s"
% (self.house_type,self.area, self.free_area,self.itme_list))
def add_item(self,item):
print("要添加 %s" % item)
# 1.创建家具
bed = HouseItem("席梦思",4)
chest = HouseItem("衣柜",2)
table = HouseItem("餐桌",1.5)
print(bed)
print(chest)
print(table)
# 2.创建房子对象
my_house = House("两室一厅",60)
my_house.add_item(bed)
my_house.add_item(chest)
my_house.add_item(table)
print(my_house)

主程序只负责创建房子对象 和家具对象
让房子对象调用 add_item 方法将家具添加到房子中
面积计算，剩余面积，家具列表等处理都被封装到房子类的内部了
