How to do this list challenge?

I have no idea how to do it.

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
group = 1
for group in musical_groups:
    print(muscial_groups[{}] [{}].format(group))

There are a few issues, here are some hints:

  • "muscial_groups" is misspelled (instead of "musical_groups")
  • it would be most unusual to place empty dictionaries in lists   "[{}]"
  • you won't need indexing "[]" for this challenge
  • you also don't need "format" here
  • but you will likely want to use "join"
