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.
Yes it is, :-)
apparently you forgot a letter :P
To be fair I mainly follow PEP8 because it's a good (imo) way to make my code more readable
In my defence, this is the first time I've ever heard of PEP-8.
here we go again, not following PEP-8
What is the purpose of the test, if you use built-in functions?
Please use spoiler flag next time.

Why didnt you had to return 0 in case the array is empty?
genius
Impressive! Definitely the cleanest solution I've found so far.
Description conflict.

How does this work??
I use codewars to train several languages and sometimes I want to write solutions in one language (for example PHP) to katas that I previously solved in other language. Then I understand that I should search for katas in language PHP with progress 'Kata I have not completed', expecting that this means 'Kata I have not completed using PHP'. But then I get katas thah I have not completed in any language. So, how can I get the katas that I've not completed using a particular language? If this is not possible, can you include this new feature? (or new interpretation of the combined selection in the search form)
Sorry for my lean english
