Hello All,

Below is the code that I had written to solve this LIST Challenge question and I got the results as well.

just though to check if the below said code is correct.

Appreciate your responses.

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"],
]
group_counter = 1
for group in musical_groups:
    print("{}".format(", ".join(group)))
    group_counter += 1

Your answer is correct but why you have variable 'group_counter'? It is not required here

Yes Vishal, there is no need for group_counter variable and it was declared for someother purpose.
