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.

Hey there! So I pass the tests that are provided and the tests that I made. Whoot. The problem is that "val" is being caught for some reason. Does anyone have any insight on that? Here's what the actual text says: "AttributeError: 'NoneType' object has no attribute 'val'"... I only use 'val' when I'm writing a.val and b.val; again, it works fine in the testing phase, but not in the attempt phase. Thanks! :D
