Python Split is Complicated for Me

The question is:

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 use .format() on our existing menu variable 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.

I'm not sure where to go from there

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

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 use .format() on our existing menu variable 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.

I would break this into parts. Let's start with the 1st sentence.

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 (", ").

So we are creating a new variable 'display_menu' that will store the sundaes list.

display_menu = sundaes

And we need to rejoin the list together by a comma and space.

display_menu = ", ".join(sundaes)

Now the next sentence.

Then use .format() on our existing menu variable to replace the placeholder with the new string in display_menu.

So, we need to use .format() on menu and join our 'display_menu' to the menu variable.

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

Your final code should look like

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