musical groups challenge

I am completely lost, i feel like i am not retaining any of this information i keep rewatching the videos and it seems like the "join" is not covered in how to interpret it into the "for, in" command. i understand how they both work (i'm pretty sure) but combining them is beyond me. please help

groups.py 
musical_groups = [
    ["Ad Rock", "MCA", "Mike D."],
    ["John Lennon", "Paul McCartney", "Ringo Starr", "George Harrison"],
    ["Salt", "Peppa", "Spinderella"],
    ["Rivers Cuomo", "Patrick Wilson", "Brian Bell", "Scott Shriner"],
    ["Chuck D.", "Flavor Flav", "Professor Griff", "Khari Winn", "DJ Lord"],
    ["Axl Rose", "Slash", "Duff McKagan", "Steven Adler"],
    ["Run", "DMC", "Jam Master Jay"],
]
groups = ", ".join(musical_groups)
for members in musical_groups:
    print(groups)

Go back to your worksheets and combine what you learned from expenses.py and meeting.py. That will help with part 1.

Hi Joel, oddly enough the simplest answers are the hardest. I spent some time going back through previous notes to find this answer. The easiest way I found was this, just adding in a for loop and joining a comma to the new group.

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