報錯內容是這樣的:

您的程式被監控系統中斷，可能是程式無法正常結束所導致。
Traceback (most recent call last):
  File "/14337166_a013/code_14337166.py", line 50, in 
    rome_num = tuple(map(rome_to_num,rome.split()))
  File "/14337166_a013/code_14337166.py", line 15, in rome_to_num
    outnum = rome_dict[rome[0]]
KeyError: '#'

但我不明白，這字符'#'不應該出現在這裡阿，我已經用if條件把他篩選掉了
我自己在PyCharm中測試也沒有問題，很順利，可是到zerojudge這邊就是會報錯

原來如此

剛剛查了一些關於 \r 的介紹，雖然還沒完全明白它的的用法，但就先記著了
