In this challenge gives an error: Bummer! Did you use `.join(", ")`? but I think it is: new = ",".join(sundaes)

I run in computer command line and I think the result is ok.

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

What the error in challenge.

banana.py 
available = "banana split;hot fudge;cherry;malted;black and white"

sundaes=available.split(";")
menu = "Our available flavors are: {}."
new = ",".join(sundaes)
menu = menu.format(new)

:point_right: The challenge asked you to join sundaes with a comma and a space. It looks like you forgot the space.

:information_source: Also, while it's not necessary to pass, you can combine the join and the format like this:

menu = menu.format(", ".join(sundaes))
