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.

Working in python, it seems that the test has integers inside nested lists.
''' The content of a dictionary item is not correct: [42740748] should equal [[42740748]] '''

Looking at the rules and examples, the result should be a list of ints, not a list of a list of ints.
