you know 3 members. So can you please only print out the trios

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

for music in musical_groups: print(", ".join(music))

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

That is my code please is this correct ???

If I remember this challenge correctly, one step has you create a loop to print out the whole list, and then the next step asks you to modify the code to print out only the trios (so you would still only have one loop).

But this code has two loops, one will print the whole list, and the other will print the trios again.
