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.

I believe that makes it into an integer, instead of string type.

There is an error in your code in checking the vowel letters.
Cheers. I've already deleted the prints, I thought that it could be the reason for that. Now it shows I've passed 4 tests. I can't figure out how to solve this empty quotations ("") issue. It works with (" ") or () though.
The message "(a) should equal (b)" means that your solution returned the answer (a), but the actual answer is (b).
In this particular case, your solution returned None, which probably means you forgot to return anything at all.
Your code is printing instead of returning the string.
Hi, can you someone explain to me what this note mean?
None should equal 'iPhone'
Does it mean that the word Phone isn't supposed to start with i, or does it mean that i() should return the word iPhone (or iWorld etc.)? I know it's a nonsense. It just drives me mad when everything works fine in vs code and it's not working here. Yeah, the only string that seems not to work in my vs code is when it's written like the empty string - i(""). In the case it's written with the space - i(" ") it works fine.
