Thank you for the hint, you helped me a lot =)

(Python) I have an error in the 6th and 9th test. The sixth test 'ab' should equal 'Ab' and the ninth test 'First of in' should equal 'First Of In' . All other tests are good . Since there is no place to look at these tests, I can't understand what's the matter. Who had a plug in this place, who can tell me?

I agree, the description is disgusting, I've read it 10 times and I don't understand what they want from us. It would be good for the author to give more understandable examples and descriptions.

and here it was a shame!)))

Here you only need your own logic of thinking =) There are many solutions to this kata, the more experience in programming, the more concise the code turns out.

0 does not return, it gives an error, but in general it is brilliant :-)
