Hi @H1kmetH4SH and welcome to Codewars!

You must return your solution, rather than print it - if you are new to the site you can read this helpful document Solving katas which will explain the most common early mistakes people make.

Also here is a useful link for Troubleshooting your solutions

Your current code looks OK to me, you just replace print(realfriends) with return realfriends - that should work.
