I couldn't pass the task 3 of the code challenge. I think my code is correct but I got the message saying: Bummer! Did you use the '.join(",")'?
available = "banana split;hot fudge;cherry;malted;black and white"
sundaes = available.split(";")
menu = "Our available flavors are: {}."
menu = "Our available flavors are: {}.".format(",".join(sundaes))

Your code is correct, except you have a small typo (kind of). The challenges are very specific and picky. This part want you to join them with "a comma and a space (", "). You are just missing the space. So...
menu = "Our available flavors are: {}.".format(",".join(sundaes))
should be...
menu = "Our available flavors are: {}.".format(", ".join(sundaes))
Keep Coding!

1,218 PointsYou are right. The challenges are very picky. I did miss a space out there. Thanks! One more thing, I have tried to put the code in another way: menu.format(", ".join(sundaes)). I tried it in the workspace and it worked just fine. But somehow the same code didn't work in the code challenge.
