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.
Regular expressions are so satisfying! Great Kata, thanks xianpants!

Sounds like you tried to find the index of an item that is not actually in the list. i.e. if my list was
['a', 'b', 'c']
and I asked for the index of'a'
I would get the value0
. If I asked for the index of'd'
however then that is not in my list so you get an error :(I got all the tests passed. Nevertheless I can't submit it, it says STDERR "index ValueError: ' ' is not in list.
What does it mean?
