Thanks boi. I'll go back and watch all the videos until I completely understand it.

In the first task input this,

for x in musical_groups:
    print(", ".join(x))

for the second task,

for x in musical_groups:
    if len(x) == 3:
        print(", ".join(x))

Even when solving this challenge now, I could not understand what exactly the challenge wants me to output, but I figured it out by trial and error.

Asking for a solution to an entire challenge will bring you no good, I'm against this method of helping but since it seems you're getting discouraged (judging but the late reply) I'd provide the solution.

I HIGHLY recommend you rewatch previous videos and understand the fundamentals strongly before moving further in the course, If you continue to ask for solutions in the future there is a 97% chance you will give up on programming.

Advice from a fellow noob programmer who struggles with every challenge.
