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.

Are blank spaces in random tests treated as characters? I mean, it's a blank space, not a typical alphabet letter so idk why it's treated as such. (used python btw)
