AssertionError Ad Rock not found in Ad Rock. My output seems correct printing all the names in the list with comma sep

Not sure what the error I am getting is asking for. Please clarify
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:
    for name in group:
        print(name, ", ")

Here's a few hints:

  • the "join" method doesn't do anything by itself, you must assign or print it
  • the string you use to call "join" should contain the separator characters
  • you only need one loop
