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"],

Indent your print function to the same position as your " a " variable, so it should look like this:

for group in musical_groups:
        a=(", ").join(group)
        print(a)

Anthony's right that it is an indentation issue, the current placement of the "print" statement causes it to be outside of the conditional block. But it also looks like the assignment is indented one step too much. So the correct indentation would actually be:

for group in musical_groups:
    a = ", ".join(group)
    print(a)

I also adjusted the styling of the assignment statement to conform to PEP8 recommendations.

You could also eliminate the variable entirely and just print the expression directly:

for group in musical_groups:
    print(", ".join(group))
