for member in musical_groups:
    if len(memusical_groups[num]) == 3:
        group_member = ", ".join(musical_groups[num])

        num = num + 1

The first issue is you spelled musical_groups wrong in your if block. Also, there is no need to check for a length of three, you just need to output the names joined together so you can remove the print statement. Also, in a for loop in python, you don't need an index as you would in java or matlab.
