[Tutor] How to remove the comma only at the end?

[Panchanathan Suresh]

Thanks a lot Mark and Alex, really appreciate it.

I thought about this more and then this worked  return members[:-2]
(-2 because there is an extra space after , in members = members + users[x]
+ ", ")

I was all along trying -1 and was unsuccessful.

Thanks again.
