what's going on here.. looks clever tho

Practically, don't think this will ever need to be scaled. It's tic tac toe. If possible future scaling isn't an issue, why even bother future proofing it?

missing test size spec in description, which is required to understand what problem needs to be solved

js tests need to be updated, missing random tests + other issues

As a new comer on Codewars, I wanted to try to translate some kata, and was inspired by this one...

So I've prepared a Python translation.

Anyone to check, comment and possibly approve ?

There should be no need to use decimals in this particular challenge, and floats should work. I tried to build the tests in the way to make them resistant to precision issues, and if you have such problems, then i believe its something not exactly right with your code.
I can double check if you post your code bere.

When using Python 3, is it recommended to use the decimal module? Is the floating-point precision so bad for doing its kata?

the initial code should be a class

Random tests are basically non-existent, only 1. Also random test is setup as such

const prefix=new Array(row).join('\n') + new Array(column).join('a') + 'Hello';

with a predefined prefix...(Solutions can easily hardcode such cases along fixed tests).....

@JohanWiltink grats on another "premature" approval !

Description also does not explain whether the match string will take the \n character into account or not. Initally I was thinking of cases like (abc\ndefc\nhu, chu)

More test examples are needed, the link to the article does not work

I had to work that one out myself. Excellent
