当你“得到”一个物品时，你想把它附加到你的物品清单上，并把它从房间里移走。
尝试以下操作：

elif command == 'get':
        current_item = castle_rooms[current_room_id]['Item']
        if current_item not in inventory:
            inventory.append(current_item)
            castle_rooms[current_room_id]['Item'] = None
            return current_room_id

如果你在第56行附近得到一个错误，那么（基于你的原始代码）可能是：

if castle_rooms[current_room]['Item'] not in inventory:
        print('You see {} in the room.'.format(castle_rooms[current_room]['Item']))
    else:
        pass

如果一个房间没有一个项目，那么这将抛出一个关键字错误。尝试将该代码替换为：

current_room_item = castle_rooms[current_room].get('Item')
    if current_room_item not in inventory:
        print('You see {} in the room.'.format(current_room_item ))

下面是一个更完整的示例：

import time

def player_instructions():
    # main menu and game commands
    print('Move Commands:\n\tgo North, go South, go West, go East')
    print("Inventory Commands:\n\tshow, take")

def player_commands(command, direction):  # function for moving rooms
    global current_room_id  # declare current room as global
    global inventory  # declare inventory as global

    if command == 'show':
        if not inventory:
            print("Your backpack is empty.")
            return current_room_id
        
        print("You have the following items:")
        for item in inventory:
            print(f"    - {item}")
        return current_room_id

    if command == 'take':
        current_item = castle_rooms[current_room_id]['Item']

        if not current_item:
            print(f"There is nothing here to take")
            return current_room_id

        if current_item in inventory:
            print(f"You already have the {current_item}")
            return current_room_id

        print(f"You greedily take the {current_item}")
        inventory.append(current_item)
        castle_rooms[current_room_id]['Item'] = None
        return current_room_id

    if command == 'go':
        if direction not in castle_rooms[current_room_id]:
            print("You can't go that way")
            return current_room_id

        print(f"You head {direction} out of the {current_room_id}.")
        return castle_rooms[current_room_id][direction]

    print('Invalid command')  # error message for invalid command

所以我和一个懂python的朋友一起工作，他教了我一些非常好的新东西，给代码添加颜色，他还帮助我解决了我的库存问题，我认为内联注解解释了它的大部分内容，我很高兴它能运行得很好。
