Thanks for the info.

I got it but I'd like to get a reasonable explanation to my question: "Why this is not fixed yet?"
Or at least an advice for a workaround.
It makes to complete this kata painful.

Few randomized tests has incorrect reference value. I can see the this is also reported a few years ago.
Why this is not fixed yet?

Ie. the reference return value should be 34 hovever the shortest path is 32.

But it is. I reload several times the page with pushing the refresh button many times.
And also delete the cookies from the browser so I must to log in again.
I opend the Kata and still Python 3.X is disabled.

What do you mean "reset the trainer", it is the "Reset" button?
I tried it many times, but 3.X interpeters are still disabled.

I always get the following error:

Traceback (most recent call last):
File "main.py", line 114, in
fixed = generate(1, size+1, size)[0]
File "main.py", line 68, in generate
generate._pool_cache.append(''.join(random.choices(combos, k=chunk_len//combo_len)))
AttributeError: 'module' object has no attribute 'choices'

10 basic tests are passed. In Python2 'choices' method not exist.
Why Python 3.X interpreters are disabled?

Thanks, it is corrected!

Many Thanks for checking correctness of this kata solutions, it seems I am beginner in translation! :)
I removed preloaded part and also removed creating globals. I hope test cannot be hacked anymore! :)

OMG! :D I tried to reload the page (Ctrl+F5 or Crtl+r) or opening it in a new tab but it seems that the service remembers everything not just your last trial! I found the "RESET" button and it refreshed accoring to my modification! :) Other interesting thing that the page says the "5 times Python has been comleted out of all kata completions" but if I view the solutions only mine is there and two wrong solutions, one of them is yours to prove the bug. Anyhow I count it it's only three.

Thanks for it! I corrected it but after either clicking on "Reset" and/or "Re-Publish" buttons in any order nothing changes on my side. I still see the old test code when I open the kata to practice!
Your wrote that: "you need to reset the trainer (button)". I don't see any "trainer" button. There is a "Trainer" option in the "Go To" drop down at the right uppper corner but I don't think that it directs to the practice page.
It's quiet unclear for me how you can see my previous update while I see the old veriosn?!

Maybe I can not undersand how "Edit Kata" option works. I have tried several times to modify the tests but it will not have any affect when click on the "train again" button. (I used the "validate solution" first and then the "Re-Publish" button.)

Thanks for the mid-sized tests, I'll fixed the tests and also tryed to disable Python2, because I think tests won't work but couldn't find it how to do?!
Can you help me with this issue as well?

Sorry for the mistakes, I corrected the tests.
Is it okay now at your side too?

Python translation kumited.

Python translation is ready but it's my first translation and I do not undersand really how it will be visible as optional language. Can anyone help on this?
