继承实例--一个房屋中介

通过一个房屋中介的实例，说明继承

*实现的功能：
- 中介掌握有所有房屋的信息
- 中介可以添加房屋，在他掌握的房屋信息中
- 房子有两种类型，有区分*

class Agent:
    # 代理类
    Property_list = []
    def display(self):
        #　通过循环呈现出所有的房产
        for each_property in self.Property_list:
            each_property.display()

    def create_property(self, name):
        # 一个代理可以创建一个新的房产在他的房产列表里面
        num_washroom = input("num_washroom:")
        area = input("area:")
        num_bedroom = input("num_bedroom:")

# 建立公寓和房子的子类

house1 = HouseProperty(name="HouseOne", area='100', num_bedroom='1', num_washroom='1', num_warehouse='1', garage='True')
apartment1 = ApartmentProperty(name="ApartmentOne", area='120', num_washroom='1', num_bedroom='2', balcony='True')

print(Agent.Property_list)
agent_one = Agent()
agent_one.display()
print(agent_one.Property_list)

agent_one.create_property("ApartmentTwo")
#　创建一个房产
print(Agent.Property_list)
agent_one = Agent()
agent_one.display()
print(agent_one.Property_list)

上述代码中，对super（）函数的使用和函数关键字参数的使用很重要

对于面对对象编程，我们主要是制造接口
