What am I doing wrong?

problem set up:

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 use .format() on our existing menu variable 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.

my code is in banana.py

Error message:

Bummer! Didn't find the right series of sundaes and commas in menu.

Why am I getting this error?

banana.py 
available = "banana split;hot fudge;cherry;malted;black and white"
sundaes = available.split(";")
menu = "Our available flavors are: {}."
display_menu = ", ".join(sundaes)
menu.format(display_menu)

:point_right: The format function doesn't change the format source, it just returns the result.

Since the challenge expects the final result in menu, you must assign the result back to it:

menu = menu.format(display_menu)
