The challenge is asking for 'output the members joined together with a ", " comma space as a separator'. It only wants the members printed with commas and space between their names like this: Ad Rock, MCA, Mike D.

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

thank you Megan

How did it work? Can you please explain me how it worked? (Sorry if my english is bad, it's my third language.)

Hie Suryansh Sisodiya. on my for loop I have to write this line of code:

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

and i managed to pass the challenge
