The first dimension is group, the second is group members. Can you loop through each group and output the members join

Please let me know what I am doing wrong here.

Thanks,

Karen

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"],
]

for member in musical_groups:
    member = ", ".join(musical_groups)
    print(", ".join(member))

This line:

member = ", ".join(musical_groups)

Is unnecessary. It in fact will override the member variable used in the loop.
