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

Hi there,

There are three things to change.

First, just leave in the first three lines of code - delete the others: 

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

Second, you want to join on a comma and a space - you've missed the space out. And, lastly, pass sundaes into the join method, not available.

You end up with:

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

Steve.

I think you did fine - I just spotted your answer wasn't quite providing the full solution. We're all just trying to help so keep it up! :+1: :smile:

Remove these lines:

display_menu=sundaes
"," .join(display_menu)
menu='Our available flavors are:{}'.format(','.join(display_menu))

and put parenthesis around 'Our available flavors are:{}'.format(','.join(available)) on the menu line. Now menu is equal to what display_menu is supposed to be. Hope this helps, Nakal

And on the 'menu' line you have ', '.join(available) It should be ','.join(sundaes)
