Hello,
"match" and "case" were new features when Python 3.10 came out. Make sure you have your Jupyter interpreter above py3.10

I tried this in Jupyter Notebooks, but the 'match' and 'case' keywords don't seem to be in my distro, can you clarify where they come from?

I agree about the bullet points layout.

In the example you gave though, "a white space" is one thing, "number of error for that letter in a field of 6" is another thing.

Maybe this would be clearer: "the number of errors as a left justified string of 6 characters long".

The white space is usually the default filling character in an aligned string (center, left or right).

I think the description of the format of the output string should be rewritten or at least elaborated on. To me, it is not at all clear what

... a white space, number of error for that letter in a field of 6, ...

means. Perhaps I'm in the minority on this but something along the lines of "the count of the error and subsequent whitespace before the '*'s should take up 6 characters" is much clearer as I don't find the word 'field' here to be intuitive. Moreover, I see no reason to try and fit the entire format description into one "sentence" and I think breaking it up into bullet points for each segment would improve clarity.

Really nice initiation and practice to those unfamiliar with class construction. Thanks for the kata!

if you hit a multi-val Lambert W function as the only possible solution to an equation in an attempt to rectify the error check involved, turn back! you've gone too far! have a few facepalms and realize the answer is pretty easy with some calc 2 knowledge. definitely add some sort of extra tag indicating the required level of math necessary maybe.

I started codewars about a week ago and this is without question one of the more creative, well explained kata I've done. Will be doing others by you as well. Thank you
