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.
The error I got had the message that I shared. :s
Please, don't be an idiot like me, and note that in Python it expects the kata to return a set, not an array.
If you get:
['1-800-CODE-WAR', '1-800-CODE-WAS', '1-800-CODE-YAP', '1-800-CODE-ZAP'] should equal {'1-800-CODE-YAP', '1-800-CODE-ZAP', '1-800-CODE-WAS', '1-800-CODE-WAR'}
That's the error.
