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

Can't get my code to work. Is there something I am doing wrong?

I have tried this out but I keep getting a "Bummer! Did you use ",".join()?" but I did...? Not sure where to go from here.

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

This was the question asked:

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.

Everything is correct except the print. Remove that and it should work.

don't worry, the description was a little confusing. However, there are a few things that will have to be changed in order to get your code to work.

  1. for the final line of the code it wants
menu = menu.format something  

instead of

 print(menu.format something)
  1. although it shouldn't make a difference,
display_menu = sundaes" 
 format(", ".join(display_menu))

it seems to need

display_menu = ", ".join(sundaes) 
format(display_menu)
  1. whew...now for the last item in your code you have (",") without space where it should be (", ") with a space

Let me know if you need any more help
