Keep calm, Nick. You just committed a minor mistake. The Interpreter is very picky, and won't allow errors of semantics. You wrote... for members in musical_groups: print("" + member)... it should have been: print("" + members).

And let me know if you have problems later on.

Cheers!

Here's the code for both tasks

for musical_group in musical_groups: if len(musical_group) <= 3: #If I only want Groups with 3 members. print(", ".join(musical_group))
