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

will I need to set up multiple while loops? or print the lines of the list required

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"],
]
while musical_groups:
    print(musical_groups[1])

You only need one loop if you use a "for" instead, since it will extract each group list from the bigger list one at a time.

Then you could use the "join" method to create the string that you want to print out.
