Python Introducing Lists Build an Application Multidimensional Musical Groups

I am unsure of how to edit a nested item

When I run this code it doesn't work, but I am not sure where my errors are.

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
for item in range(len(musical_groups)):
    print(item + ", ")

If item is an integer, how are you combining it with a string?
