Loading collection data...
Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.

Why is this lower ranked the valid paren kata?
So I ranked up to 5 Kyu doing purely SQL katas. I'm good with that for now, and I want to switch over to some Python training. Is there a way to keep track of Kyu level in different languages like Python and SQL?
This looks really clever. Where is this functionality documented?

The problem should say to return float.
Yeah very confusing
I read that Python 3 is available, but how do you distinguish between 2 and 3 in the katas?
I think this solves the test cases, but doesn't generalize more than 1 nested list deep.
