Have no idea what to do for step 2

I am passing step 1 but not even 100% I am doing that correctly. I've tried everything I can think of. I'm noticing after running the for loop these groups are no longer in a list but I don't understand how to call the groups (bands).

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:
    print(", ".join(member))

You just need a simple if condition before the print statement.

for group in musical_groups:
    if len(group) == 3:
        print(", ".join(group))
