Hi Everyone,
Its asking if I used '.join' ???
I really have no idea where im going wrong
available = "banana split;hot fudge;cherry;malted;black and white"
sundaes=available.split(';')
menu="our available flavors are: {display_menu}."
display_menu= "sundaes" + ",".join("available")

There are a few things wrong here. The "{}" is a place holder for you to fill in using .format. If you want to solve this challenge in one line you would write the string as "our available flavors are: {}." and then format that string to insert the joined sundaes.
Try this:
available = "banana split;hot fudge;cherry;malted;black and white"
sundaes = available.split(";")
menu = "our available flavors are: {}.".format(", ".join(sundaes))
Let me break this down:
sundaes = available.split(';') # Returns a list of sundaes
menu = "our available flavors are: {}".format(", ".join(sundaes)) # Formats the string with ", " between each item in the sundaes list
