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.
Just give 'wolf' in a if condition and check it with last element.Looping is not necessary for this problem.
Please once again read the kata description properly and then proceed.
It seems that wolf list is empty, so you can't use wolf[-1] it will result in Indexout of range or print nothing.
