這是問題所在：
一切似乎都很好，直到有幾個人搬進來時它壞了，我剛走進的房間給了我一個“KeyError：None”。我不知道是什么原因造成的，而且我是新手，所以請簡化對我的解釋。我認為它與 findExits() 函式和 findRoom() 函式有關，但 idk.
這是 TraceBackError：
Traceback (most recent call last):
File "main.py", line 287, in <module>
player.Move(command)
File "main.py", line 26, in Move
self.room = world[newRoomName]
KeyError: None
我試過擺弄這個功能，但我試過的一切都沒有奏效。這是 repl.it 鏈接：https ://replit.com/@samsonsbrother0/Dungeon-Crawler#main.py
uj5u.com熱心網友回復：
您的代碼在密鑰存在之前訪問它，因此出現錯誤。要修復它，您需要在移動時將 newroomname 分配給 world dict，如下所示：
print("Moving to", newRoomName)
world[newRoomName] = newRoomName
self.room = world[newRoomName]
