While not explicitly stated, in the second task you were supposed to change the for loop from task 1 rather than add a new one. If you remove the first for loop in your solution then your code will pass.
Also as an aside try to avoid making multiple questions for the same challenge, or at least delete your old questions before making a new one. If you don't then people might provide answers to your old posts without realizing you have already solved the issue. I've gone ahead and deleted your two other posts for you.

But part 2 fails, because the automated test wants is to only see the trios, not the lists from part 1. So if you comment out (or leave out the code from part 1, you will pass the "trio" tests for part 2 of the challenge.
Good luck with Python, it's a worthwhile journey!
