use .split() and .join()

how can I reassign the menu variable to use the existing variable and .format() to replace the placeholder with the new string in 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 = ",".join(sundaes)

The use of join is incorrect. Flip the object and the argument:

display_menu = ",".join(sundaes)

For the last part, you can use .format on menu with the argument display_menu and reassign the result back to menu

Post back if you need more help. Good luck!!!
