楼房销售系统代码python

以下是一个简单的楼房销售系统的 Python 代码：

class House:
    def __init__(self, address, price, area, rooms):
        self.address = address
        self.price = price
        self.area = area
        self.rooms = rooms

class Salesman:
    def __init__(self, name, commission):
        self.name = name
        self.commission = commission

    def sell_house(self, house, buyer):
        if buyer.budget >= house.price:
            buyer.budget -= house.price
            self.commission += house.price * 0.1
            print("Congratulations, " + buyer.name + "! You have successfully purchased " + house.address + " for " + str(house.price) + " dollars.")
        else:
            print("Sorry, " + buyer.name + "! You cannot afford " + house.address + ".")

class Buyer:
    def __init__(self, name, budget):
        self.name = name
        self.budget = budget

salesman = Salesman("John", 0)

house1 = House("123 Main St", 500000, 2000, 4)
house2 = House("456 Elm St", 300000, 1500, 3)
house3 = House("789 Oak St", 700000, 2500, 5)

buyer1 = Buyer("Alice", 600000)
buyer2 = Buyer("Bob", 400000)

salesman.sell_house(house1, buyer1) # Congratulations, Alice! You have successfully purchased 123 Main St for 500000 dollars.
salesman.sell_house(house2, buyer2) # Sorry, Bob! You cannot afford 456 Elm St.
salesman.sell_house(house3, buyer2) # Congratulations, Bob! You have successfully purchased 789 Oak St for 700000 dollars.

这个系统包含三个类：House、Salesman 和 Buyer。House 类表示一栋房子，包含地址、价格、面积和房间数等属性。Salesman 类表示销售员，包含名字和佣金等属性，以及一个 sell_house 方法，用于销售房子。Buyer 类表示买家，包含名字和预算等属性。在主程序中，创建了三个 House 对象和两个 Buyer 对象，然后调用 Salesman 的 sell_house 方法进行销售。如果买家的预算足够支付房子的价格，销售员会计算佣金并打印一条祝贺消息；否则会打印一条失败消息。
