7,767 PointsPretty sure my output is correct, not sure why i'm not passing the code challenge 1 of 2
Here's my code:
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 members in musical_groups: ", ".join(str(musical_groups)) print(members)
I must be missing some concept to grasp here. Has anyone successfully finished this code challenge?
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 members in musical_groups:
", ".join(str(musical_groups))
print(members)

Treehouse Moderator 28,720 PointsLooks like you get the concept of join() method, let's build on that.
The way you wrote your loop was spot-on-- good work!
The join() method needs a little work, since we want to join members into a string (like mystring in the example below).
for members in musical_groups:
# each time we go through the loop, members is set equal to a list of members
# lets JOIN the members with commas and CAPTURE it into mystring
mystring = ", ".join(members)
# now, print it out.
print(mystring)
On part two-- the Challenge asks for ONLY trios.
for members in musical_groups:
# each time we go through the loop, members is set equal to a list of members
# lets JOIN the members with commas and CAPTURE it into mystring
# PART 2, print only the TRIOS
if len(members) == 3:
mystring = ", ".join(members)
# now, print it out.
print(mystring)
