how would i block out non trios?

if tried everything, but i still can't block out the non trios. I know the way i did task 1, is pretty stupid, and probably should have used a function.

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"],
]
# Your code here
b = musical_groups [0]
a = musical_groups [1]
n = musical_groups [2]
d = musical_groups [3]
i = musical_groups [4]
t = musical_groups [5]
s = musical_groups [6]

bands = b + a + n + d + i + t + s


for g in musical_groups:
  g = ", ".join(bands)
if len(bands)  :
    del bands


print(g)

Hmm what is g in your for loop?

Remember a two dimensional list is just a list of lists.

Let me know if that hint doesn't do the trick ;)
