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"],

Nikhil, you are so close!

Steven is right... join is a method on a string that takes a list as its parameter.

This example should clarify things for you.

Python 3.6.4 (v3.6.4:d48eceb, Dec 19 2017, 06:04:45) [MSC v.1900 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>>
>>> shopping_list = ['milk','bread','eggs','carrots']
>>> print(shopping_list)
['milk', 'bread', 'eggs', 'carrots']
>>> shopping_str = ", ".join(shopping_list)
>>> print(shopping_str)
milk, bread, eggs, carrots
>>>
