While I was busy with this error, I already solved the kata "DecipherThis".

I will check. I’ll write as a result.

Hello. Python. My code passes sample tests or example tests. (If necessary, I can send, but not here.) But, when there is a full test suite, it produces an almost random number of errors, from 25 to 40. Everything is always identical, except for the differences. The differences between my answer and the solution are always the following:

Answer - 82hbdOh
My - 104RbdOh

Answer - 120YSuUNY
My - 89xSuUNY

Answer - 89rjXpYJBzwwOUnCphr
My - 114YjXpYJBzwwOUnCphr

Here people wrote about double spaces, but this is not a space. And about the fact that always if a word is two letters, then the letters should be interchanged, probably not true, because in the model tests this is not there, in the description either, and in more than half of the full tests there are no errors.
I am writing as a last chance. Because I’ve been here for 3 hours on this error. Thanks for everyrhing.
