I dont understand this question

Please explain

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

Hi Salem,

I spotted two mistakes in your code:

1) The join() method actually works the other way around: you define the elements with which you separate the string elments (of the sundaes list) at the beginning, and the name of the list for which you do that at the end, like this:

display_menu = ", ".join(sundaes)

2) You do not have to use join() again afterwards, as display_menu then already contains the correctly formatted string. You can just format the menu variable with display_menu (add the following code as a new command, otherwise the previous tasks will no longer pass):

menu = "Our available flavors are {}.".format(display_menu)

or (more elegantly) like this:

menu = menu.format(display_menu)

So in the end it looks like this:

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

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