Loops and groups

How do I loop through each group? I am feeling lost.

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"],
]

print ("Musical Groups:")
group_number = 1

for group in musical_groups:
    members = ""
    if group_number > 1:
        group_size=len(group)
        print "len = " + str(len(group))
        for position in range(0,group_size):
            members = members + group[position] +", "
        print members
    group_number += 1

The instructions to "loop through each group" are perhaps a bit misleading. The task is actually to loop through the list of groups.

For each group you can just "join" the items using the correct separator characters.
