Python Introducing Lists Build an Application Multidimensional Musical Groups

for loop

I have 0 idea what to do here. The bottom of the code is the best I can think of but I know I'm missing a few steps:

Here is a multi-dimensional list of musical groups. The first dimension is group, the second is group members.

Can you loop through each group and output the members joined together with a ", " comma space as a separator, please?

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 members in musical_groups:
    members = ", ".join(musical_groups)
    print(members)

You have the right idea, but its the members you want to join (not "musical_groups"). And to avoid confusion, it might be best to assign them to a new variable (with a different name).
