You are really close!

#Your Code
for musical_group in musical_groups:    #Line 1
    print(musical_groups.join(", "))     #Line 2
  • Line 1: This is correct
  • Line 2: Two things to correct. Remember that in your ** for...in** loop, you have musical_group as the variable that will be assigned to during each loop/iteration. With that in mind, you need to have musical_group as the value in your print statement. Additionally, the join method is being called incorrectly. It is called before the object being affected as in the example below:
print(", ".join(some_object))
  • Once you have those things corrected, you're off to the races.
