用Python面向对象写一个宾馆管理系统

好的，宾馆管理系统可以分为以下几个部分：

1. 客房信息管理：包括房间号、房型、价格、状态等属性

2. 顾客信息管理：包括姓名、电话、身份证号、预订房间号等属性

3. 订单管理：包括订单号、顾客信息、房间信息、订单状态等属性

基于以上需求，可以构建以下类：

# 客房信息类
class Room:
    def __init__(self, room_number, room_type, price, status):
        self.room_number = room_number
        self.room_type = room_type
        self.price = price
        self.status = status
        
    def __str__(self):
        return f"房间号：{self.room_number}，房型：{self.room_type}，价格：{self.price}，状态：{self.status}"
        

# 顾客信息类
class Customer:
    def __init__(self, name, phone_number, id_card, room_number=None):
        self.name = name
        self.phone_number = phone_number
        self.id_card = id_card
        self.room_number = room_number
        
    def __str__(self):
        return f"姓名：{self.name}，电话：{self.phone_number}，身份证号：{self.id_card}，预订房间号：{self.room_number}"
        

# 订单管理类
class Order:
    def __init__(self, order_number, customer, room, status):
        self.order_number = order_number
        self.customer = customer
        self.room = room
        self.status = status
        
    def __str__(self):
        return f"订单号：{self.order_number}，顾客信息：{self.customer}，房间信息：{self.room}，订单状态：{self.status}"

接下来是宾馆管理系统类：

class HotelManagementSystem:
    def __init__(self):
        self.rooms = []  # 客房信息列表
        self.customers = []  # 顾客信息列表
        self.orders = []  # 订单信息列表
        
    # 添加客房信息
    def add_room(self, room):
        self.rooms.append(room)
        
    # 添加顾客信息
    def add_customer(self, customer):
        self.customers.append(customer)
        
    # 添加订单信息
    def add_order(self, order):
        self.orders.append(order)
        
    # 根据房间号查询客房信息
    def search_room_by_number(self, room_number):
        for room in self.rooms:
            if room.room_number == room_number:
                return room
        return None
    
    # 根据订单号查询订单信息
    def search_order_by_number(self, order_number):
        for order in self.orders:
            if order.order_number == order_number:
                return order
        return None
    
    # 查询所有客房信息
    def display_all_rooms(self):
        for room in self.rooms:
            print(room)
            
    # 查询所有顾客信息
    def display_all_customers(self):
        for customer in self.customers:
            print(customer)
            
    # 查询所有订单信息
    def display_all_orders(self):
        for order in self.orders:
            print(order)

以上是一个简单的宾馆管理系统的实现，根据需求可以进行扩展。
