    Python’s re also only supports non-overlapping matches and only one direction, so what I did was

    spoiler

    I looked for the first digit/word using the regex. Then for the last digit/word, I inverted the string and the regex (so I was matching the words eno, owt, eerht, etc.) and took the first occurence, and inverted that in case it was a word, and then I had my last digit. I just had to pay attention to only include the |\d after inverting the regex, since d\| is not right.

    There are probably more elegant ways, but I couldn’t come up with anything as simple as this.

      Oh, cool, I did pretty much the same thing, just finding the words manually instead (didn’t want to use any external libraries, so I just wrote a function to search for me. Haskell doesn’t have much for OOT B functionality).
