How can I solve this challenge?

I need to print out the Trios out of these... I tried everything, googled it, searched on many websites, reviewed the videos I watched previously, I couldn't find anything that would help me I don't know I'm just lost, I just need an answer in code... not text.. Thank you!

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
Z = ", "
for group in musical_groups:
    print (Z.join(group))

print (group [0][2][6])

Without the print statement on the last line, your code passes task 1 just fine. Are you still having trouble after removing that?

Task 2 of this challenge asks you to only print out a group if it has 3 members. You'll know a particular group has 3 members because the list of members will have 3 items in it. To pass task 2, you can use the len function to check how many items are in the list you're inspecting, and if it has 3, you print out exactly what you did before. However, you only want to print something if a particular group has 3 members in it

Yess! I got it! ------ if len(group) == 3:

Thank you very much for the hint!
