I am stuck with the following quiz:
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.
This is my answer:
available = "banana split;hot fudge;cherry;malted;black and white"
sundaes = available.split(";")
menu = "Our available flavors are: {}."
display_menu = sundaes.join(", ")
menu = menu.format(display_menu)

230,688 PointsIt looks like your arguments are swapped.
It may look odd, but join is a string method that takes a sequence argument. You've applied it to a sequence and gave it a string argument.

5,971 PointsSo, the issue was on line 4. I have swapped my arguments and this has resolved my issue.
The correct syntax now is: display_menu = ", ".join(sundaes)
Thanks
