# Your code here

Here is a multi-dimensional list of musical groups. The first dimension is group, the second is group members.

Can you loop through each group and output the members joined together with a ", " comma space as a separator, please?

You're on the right track but working too hard:

  • you only need one loop
  • the "join" needs to add a comma and space between "each" item
  • the "print" won't need any special end condition
