Since you got through part 1 of the challenge, part 2 requires a slight modification of the code you supplied to pass part 1. It is easy to interpret the challenge such that you write a second loop to do part 2, but no... the challenge is asking you ONLY to modify the code from part one.

Hint, instead of just printing out each group, check to see if the length of the group is 3 (a trio) before you print it out.

Keep trying and you'll get it.

Good luck with your Python journey!!
