So, this kata just doesn't apply to the Python language - do I get that correctly? Sorry for the trouble. I am just confused. I kind of see why it wouldn't apply to Python because I didn't translate the kata as it is, but changed a part of it.

What translation?

I'm awfully tempted to take the liberty of pressing that red reject button. Both the problem and the solution doesn't apply to python. It does not translate. This translation shouldn't exist.

"In Python, strings are provided instead of bytes, as Python lacks a 'byte' data type, unlike some other programming languages."

The modified paragraph provides a brief explanation of why Python uses strings instead of bytes, making it clearer for readers who may not be familiar with the differences in data types between programming languages. This additional clarity enhances the informativeness of the text.

It could be many things, for instance: your code includes numbers from 11 to 256, or you've written functions that contain forbidden characters. You should read the text more thoroughly. Hint: sometimes the simplest things work best.
