I updated the description by copying Python version, then removed opposite kata link because there's no Rust version yet.

I fixed random test bug, according to Python version.
What part of description should I change?

I published again. Could you check I've done it right?

Initially the random test just generate any random number in range.
After you pointed it out, I copied Python random test code and adjusted it.
I have no idea what can go wrong except that.

Could you provide example test input that is invalid? Thank you again :)

My bad. I updated the random test. Thank you for your feedback.

I updated the test code according to your comment. Thank you.

It was my misunderstanding of the kata. I parsed text, not title. :|

Given sample test cases (not the one that checks solution when submitted) have hard-coded expected values.

Anyway, I will try this kata again. Thank you for the information.

It depends on which version of Python you're using. Try 3.6+.
