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.

If you look at the name of the function one is
reverseseqand the other isreverse_seq; this is why they are grouped separately - from looking at the comments the function name was changed to be more Pythonic at some point in the past. I wouldn't worry too much about it.Why is this listed as a separate/different solution from the one with most "Best Practices" votes, when they are 100% identical?
