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.
Get started now by creating a new collection.

string.ascii_letters.index(char) + 1but the kata itself doesn't have tests for that so even without that it's working properly :(This comment is hidden because it contains spoiler information about the solution
