Python Development Techdegree Graduate 8,186 PointsWhat am I missing?
I'm still having a hard time trying to understand the multi-dimensional lists sometimes especially with the loops
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"],
]
def test(musical_groups):
for group in musical_groups:
print(", " + musical_groups)
test(musical_groups)

230,688 PointsYou're getting close, here's a few hints:
- inside the loop, you'll want to work with one group at a time instead of the entire list
- when they said "output the members joined together" it was a hint to use the string join method
- you don't need to create and then call a function (but you may if you prefer)

for group in musical_groups: ", ".join(musical_groups) print(group)
It says that there's 2 problems with the code and to look on the preview pane for more information but I still don't understand completely

230,688 PointsYou're still joining the entire list (musical_groups) instead of the current group, and you need to print the results of the join. Just doing the join by itself doesn't save the result anywhere.
