menu = "Our available flavors are: {}.".format(", ".join(sundaes))
## or ##
menu = menu.format(", ".join(sundaes))

No, you are not supposed to create a new variable.
Here you need to use the format method on the menu string that you have created in task two, and not on the sundaes variable. .format() inserts whatever is in parenthesis where the placeholders {} are. So, what I can see in your code is that your format method is very close to perfection (it still has a mistake in the parenthesis but it is also applied to sundaes, which is not what you need here.

7,279 PointsHello,
I actually missed (", ".). i wrote .format(join(sundaes)) so that's why i got it wrong

menu = "Our available flavors are: {}".format(", ".join(sundaes))
#Correct Code below
menu = "Our available flavors are: {}.".format(", ".join(sundaes))
