I'm not sure what I am doing wrong, for I think I am getting the proper output, but it says it's wrong.

I get the proper output from the question, but it says it is still wrong. Maybe I don't know what the question is asking me to do and how it wants the output. Could someone provide what the output should look like? Thanks.

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 hee
for musical_group in musical_groups:
     print(", ".join, musical_group,", ")

# I changed the print line and got the output to work. Since .join is a method of the 
# strings class it needs to have parenthesis around the argument in join
for musical_group in musical_groups:
     print(", ".join(musical_group),", ")
