所以我正在为我的班级制作一个游戏。它是基于文本的，使用各种房间和物品来完成游戏。我已经找到了一种在房间之间移动和获取物品的方法。我还有一个清单功能，可以从清单中删除物品。
我遇到了麻烦，因为房间没有条件验证。如果你在开始房间'spawn room'，那么唯一有效的方向是南。当我输入北它应该给予一个语句，并重置提示，但相反的代码与KeyError中断：“North”。错误语句位于第89行和第56行。
另一个小问题是我的库存系统。如果你不输入“Set Down”，它仍然会提示下一个if语句。
我试过让方向不设置为特定房间的方向，但似乎不起作用。例如第92行
对于清单，我还尝试了不同的缩进方式，这样第二个print语句只有在用户键入'SetDown'时才出现，但是if和while语句不起作用。
