Interesting. I understand now.
Note that the code is no longer restricted to just that one version of Python - it works in the latest version (3.12) just fine. If you change the language in the heading back to just "Python" then the leaderboard will group this answer correctly with the other Pytho... (more) |

No need to apologise. I don't feel that I have any obligation to test answers, I just sometimes like to out of curiosity.
I see you have since made the code even shorter. I have no idea how it works, but it does... (more) |

I know this isn't consistent with how semantic versioning is supposed to work, but it's my best current guess at why it doesn't work on my machine.
I suppose it's also possible there's an inconsistency between operating systems. I tested this on Linux (Fedora 39), on python 3.8.19, 3.9.19, 3.10.14... (more) |

It looks like there was a lot of discussion about whether to permit assignment expressions in comprehensions when they were first introduced in python 3.8. It may be that a change was made to python 3.9 after the version you are using. When I run the 222 byte version on python 3.9.19 I get an error m... (more) |

Would it still work if you replace
```python
range(3)
```
with
```python
0,1,2

| Comment | Post #291091 |
When the input is a valid Roman number, the output does not need to be specifically the string "VALID". From the first bullet point of the Output section, you just need to "output a consistent value" which "must not be one of the strings from the list of 50".
Hopefully this saves you some bytes. (more) |

If not, output the substring that proves this, from the list of 50 strings described below.

Another possible challenge:
Given a string of Roman numerals, output either "valid" or a string from the list of 50 that proves it invalid. This may involve the Kolmogorov complexity challenge as a subchallenge. Is this good or bad? (more) |

| Comment | Post #291002 |
As written, the challenge is simply to validate a string of Roman numerals. I suspect that in most languages the golfiest way will be regex, and the list of 50 substrings will not be used. As such, they are irrelevant background info about Roman numerals, rather than being part of the challenge. I'm ... (more) |
