python酒店管理系统

下面是一个简单的Python酒店管理系统的示例代码：

class Room:
    def __init__(self, room_number, room_type, status):
        self.room_number = room_number
        self.room_type = room_type
        self.status = status

class Hotel:
    def __init__(self, name, rooms):
        self.name = name
        self.rooms = rooms

    def check_in(self, room_number):
        for room in self.rooms:
            if room.room_number == room_number:
                if room.status == "available":
                    room.status = "occupied"
                    print(f"Room {room_number} checked in.")
                    return
                else:
                    print(f"Room {room_number} is not available.")
                    return
        print(f"Room {room_number} does not exist.")

    def check_out(self, room_number):
        for room in self.rooms:
            if room.room_number == room_number:
                if room.status == "occupied":
                    room.status = "available"
                    print(f"Room {room_number} checked out.")
                    return
                else:
                    print(f"Room {room_number} is not occupied.")
                    return
        print(f"Room {room_number} does not exist.")

    def get_available_rooms(self):
        available_rooms = []
        for room in self.rooms:
            if room.status == "available":
                available_rooms.append(room)
        return available_rooms

    def get_room_status(self, room_number):
        for room in self.rooms:
            if room.room_number == room_number:
                return room.status
        return f"Room {room_number} does not exist."

    def get_rooms_by_type(self, room_type):
        rooms_by_type = []
        for room in self.rooms:
            if room.room_type == room_type:
                rooms_by_type.append(room)
        return rooms_by_type

# create rooms
room1 = Room(101, "single", "available")
room2 = Room(102, "single", "occupied")
room3 = Room(201, "double", "available")
room4 = Room(202, "double", "occupied")
room5 = Room(301, "suite", "available")

# create hotel
hotel = Hotel("My Hotel", [room1, room2, room3, room4, room5])

# check in a guest to room 101
hotel.check_in(101)

# check out a guest from room 102
hotel.check_out(102)

# get available rooms
available_rooms = hotel.get_available_rooms()
for room in available_rooms:
    print(f"Room {room.room_number} is {room.room_type} and {room.status}.")

# get status of room 101
print(hotel.get_room_status(101))

# get rooms by type
single_rooms = hotel.get_rooms_by_type("single")
for room in single_rooms:
    print(f"Room {room.room_number} is {room.room_type} and {room.status}.")

这个示例代码定义了两个类：Room和Hotel。Room表示一个酒店房间，包括房间号、房间类型和状态。Hotel表示一个酒店，包括酒店名称和所有房间的列表。Hotel类有几个方法，包括check_in、check_out、get_available_rooms、get_room_status和get_rooms_by_type，用于管理房间的入住、退房、获取空闲房间、获取房间状态和按类型获取房间等功能。
