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.

Got basically the same thing. It's good to know heapq but for a simple logical task it's nice to be able to do it with no library, though I admit I was cringing a bit at my own till[till.index(min(till))], an obviously redundant and costly operation.
Test cases marked as True or as False by a few decimals points, depending on whether some multiplication is put first or last. That is a serious bug. Test should not exactly compare floats !
