Rejoining a split string

Task: 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: {}."

*what is wrong on the next line display_menu = sundaes.join(", ") menu = "Our available flavors are: {}." .format(display_menu)

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

You were really close on this you only made one minor mistake. You're calling join on the list, which is the way you would do it in most other languages, but in python you actually call join on the string you're using to join your list followed by your list. 

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