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.

Yes, that is intended. Empty lists ( empty strings ) are perfectly legal and should be handled.
In fact, there should really be a fixed test with an empty string; testing solution behaviour for that input should not be left to the vagaries of a random generator.
This is my first bit of discourse so forgive me if I've not done this correctly.
Is it intended that the Python random tests sometimes test against an empty string?
