lol why was this downvoted

Still easy to cheat...

1. not an issue
2. when someone ask for more information, it would be nice of you to answer to this question
3. I already told you what's going on about that below.
4. moreover, that line of code isn't even executed during the tests, so that's only caused by the version of python you're currently using (the compilation fails because of the f'...' format string)

So, I'd like to know if you changed the trainer language version your self or if it was by default in something else than 3.6.0? (because that wouldn't be normal, considering it's set by default in the editor... :/ )

question: did you already attempt the kata a long time ago or was the version incorrectly set in the trainer? Because in the edit panel, it's supposed to be in 3/6 by default.

the kata is supposed to be made in python 3.6.0, not 3.4.3 or even 2.6.7.

print('\n'.join(f'{k}: {v}' for k,v in C.items() if k not in ('wLen','sLen')))
                ^^ python 3.6 syntax

Very clever solutions. Thank you for your suggestion, I'll add it to the tests! EDIT : your suggestion doesn't seem to work; itertools is there by default. I changed the "forbidden word" to itertools.

Good point, will add that.

Hi Sychov, if the pair is even then the highest remaining card wins.

I know I could do it like this. You even can see it that I used it this way for is_set and I commented there that it can be done with cycle.

In the beginning I used this for more transparency and better understanding.
