sure, does it work now? :)

It's different in a way that for Java, Codewars runner does not create a test result entry per assertion, but per test case. That's why you do not see 200 green lines even though there's 200 assertions in random tests, but only two: one for fixed tests, and one for random tests.

yeah, sure.

there are actually 2 kind of "forks":

• kumite are unrelated to any kata (third icon in the menu bar on the left)
• forks of solutions, like this one.

Forks can be used to show/suggest/discuss anything that is a deviation of the original code, being the solution of the user, the tests or anything else. Here, I forked your solution to edit the random tests and show you what I had in mind, instead of posting it in the discourse (where it's not runnable).

clearer?

Nice first kata and I hope there will be more.

Examples of embedded images: http://snippi.com/s/g4a6emp

Note how embedded images inflate description, try to keep them small if you go this way.

You cannot attach images directly to kata, but you have a couple of options:

• upload an image to external server and put it in description with markdown: ![](http://path.to/image.png)
• use svg markup directly in the description - not 100% sure if it works, but worth a try
• use <img/> tag with Base-64 encoded content of SVG image. Some kata do this (I think this one). If you create an SVG with your image, we can work it out from there.

I'm with python 3.7

nope ;)
Your ide is in 3.7. But on cw, you're using one of those only: 2.7.6, 3.4.3, 3.6.0.

Sometimes I would get passed on 12th test and then failed the next time without making any changes to the code.

maybe because some tests are random?
That or you're using a dict, with an older version of python here (before 3.6): in 3.6+, dict are "ordered", but they weren't before. That may be the reason. => use 3.6.0.
