正在为 Python 脚本课程介绍项目工作。该项目是从他们提供的一些基本代码开始构建游戏，以创建一个冒险，带您穿越多个房间，沿途收集物品。我已经能够满足大部分要求，但是在将库存系统添加到游戏后，它的处理变得非常缓慢，并且还对游戏的进行方式造成了问题。我毫不怀疑代码效率低下，可以重新组织或只是使用不同的循环。
在让库存系统按要求运行之前，需要用户输入方向，告诉您它是否是正确的房间，如果房间中有物品，您将输入移动，然后移动到下一个房间，如果它是正确的。现在，当游戏开始时，它会向您显示没有物品的正确房间（正如预期的那样），您输入一个移动，现在处理下一步移动非常。然后它会显示该物品并提示您在房间中显示您的库存，它应该向您展示房间中的哪个位置，有一个项目，以及您的库存是什么。
如果有人能帮助指出我做错了什么，我将不胜感激。

前两个建议：
我强烈建议您在遇到此类问题时，在调试器中逐步调试您的代码。我怀疑如果你这样做了，你会很快看到问题，因为你会进入问题代码行并意识到发生了什么。或者至少，您可以将问题保存给其他人，并按照建议生成产生问题的较小 MRE。
此外，在这种情况下，如果您的代码确实会减慢速度而不改变结果，那么“存根”可能会很方便。例如，如果您将所有对 time.sleep 的调用替换为对如下函数的调用：
REALLY_SLEEP = False
def sleep(value):
if REALLY_SLEEP:
time.sleep(value)
else:
import inspect
print(f"**** Sleep called for {value}s at {inspect.stack()[1].lineno} ****")
然后，您可以在测试和开发程序时快速运行程序，并在准备好供其他人使用时将 REALLY_SLEEP 标志设置为 True。
所有这一切都说：当你搬到另一个房间时，你不会花很长时间，你会花很长时间：
if player_move in rooms[currentRoom]:
currentRoom = rooms[currentRoom][player_move]
addItem = input(' \n')
此代码检查用户是否输入了有效的移动，如果输入了，则移动到新房间，并等待用户输入，而没有任何用户可以检测到的输入提示。 addItem 未使用，因此我假设它是早期迭代中被遗忘的随机代码。摆脱那条线，一切都会好起来的。
这又回到了我的开篇建议：学习在 IDE 中或不在 IDE 中使用调试器，单步执行代码将立即显示它在做什么。
