Recall that .join is tricky and kind of "backward" from how you might expect it to be used.
If you want to join the list sundaes with the string ", ", you need to actually call the join method on the string and not the list. You're essentially asking the string to join the list, rather than asking the list to join its members with a string.
Like, "Hey comma and space, join up this list for me."
menu = "Our available flavors are: {}.".format(", ".join(sundaes))
You don't have to combine all that in one expression, either. You could join up the sundaes list, store it in a variable, then plug the variable into the format() method if you'd like.
