Just curious if this kata has been updated lately? I seem to be able to return all of the correct strings in the test cases but I keep getting a key error with a random letter?

it looks something like this: KeyError: 'w'

Im pretty novice but I feel like Im at my wit's end trying to figure out what this error is complaining about.

Ok! Thank you for the quick response!

That's a problem with your code, not a kata issue, please read this: https://docs.codewars.com/training/troubleshooting. Don't mutate the list you iterate through, you'll skip values like that. Use pythontutor to visualize how your code works.
