房间如何转换自定义对象

class Room:
    def __init__(self, room_id, room_type, capacity, is_available):
        self.room_id = room_id
        self.room_type = room_type
        self.capacity = capacity
        self.is_available = is_available

    def to_dict(self):
        return {
            'room_id': self.room_id,
            'room_type': self.room_type,
            'capacity': self.capacity,
            'is_available': self.is_available
        }

# 示例用法
room = Room('101', 'Standard', 2, True)
room_dict = room.to_dict()
print(room_dict)
