Trying to loop through each list of members in musical groups but cant quite remember how to run the code correctly

In the lessons they went over splitting and joining smaller lists. and then adding groups of lists and displaying the total in a list. but not quite separating the list and then displaying it with commas. ive tried using .join and .split to separate them by the ", " but i cant seem to get the right syntax

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"],
]

musical_groups = 1 
for members in musical_groups:
    members = ",".join(members)

You're close, here's a few hints:

  • don't re-assign "musical_groups", use the one provided by the challenge
  • they want you to "print" the joined lists, don't assign anything with them
  • the instructions ask for a ", " comma space as a separator (not just a comma)
