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"],

You need to iterate through the musical groups to see which ones have a length of three. The first group would be musical_group[0] and the second musical_group[1] and so on. Length of the group can be ascertained by len(musical_group[0]). etc. You'll have to create a variable for a counter too. Good luck!
