for group in musical_groups:
    print((', '.join(group)))

Since musical_groups is a list of lists, group references each one of those nested lists individually. passing group into .join basically says "Hey, I want to take each member of the list and join them together into one big string. The ', ' part of the .join says "This is what I want to put in between each thing that I join together". Hope this helps.
