Error

Awesome! Now I'd like to see only groups that are trios, you know 3 members.

So can you please only print out the trios? It should still use the joined string format from task 1.

I don't know why its still giving me an Error. Please help

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

for group in musical_groups: 
        if len(group) == 3: 
            print('. '.join(group))

You pretty much have it. Just delete the first for loop block, and for the second one, make sure to print the group using commas (like in your first for loop block).
