The Python join is a little odd compared to its JavaScript counterpart. The join() is a string method which "glues" a list together with the string in between each member.
this_group = ["Harry","Ron","Hermione"]
this_string = "-".join(this_group)
print(this_string)
Will output this:
Harry-Ron-Hermione
You got the correct concept of looping through the musical_groups. Good job there. You also understood we could put members together with the "join" statement.
The "for" loop iterates through musical_groups. So on each iteration of the loop the variable group is instantiated with a list containing the members of one of the groups.
so... you can replace the body of the for loop with your idea about members = ", ".join(group)
for group in musical_groups:
members = ", ".join(group)
print( members )
Good luck on your Python adventure!
