Python Python Basics (2015) Python Data Types Use .split() and .join()

Can one of you help with the below question, please?

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: {}."
display_menu = "sundaes"

Remember that to insert the "sundaes" variable into the menu, you will need to use the .format() function on the menu variable. Another hint is that to make the sundaes variable into a string where each flavor is separated by a comma and space, you should try using ", ".join(sundaes). Hopefully this will point you in the right direction!
