Alright, let's finish making our menu. Combine the sundaes list into a new variable named display_menu, where each item in the list is rejoined together by a comma and a space (", ").

Then reassign the menu variable to use the existing variable and .format() to replace the placeholder with the new string in display_menu.

If you're really brave, you can even accomplish this all on the same line where menu is currently being set.

    available = "banana split;hot fudge;cherry;malted;black and white"

sundaes = available.split(";")

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

display_menu = ", ".join(sundaes) menu.format(sundaes) = display_menu

banana.py 
available = "banana split;hot fudge;cherry;malted;black and white"

sundaes = available.split(";")

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

display_menu = ", ".join(sundaes)
menu.format(sundaes) = display_menu

You are very close. The first join() is causing an error by using a period instead of a comma.

:point_right: Remove the join from the first menu statement

:point_right: the last statement should be of the form menu = menu.format(display_menu)
