The "check work" step is stating that Step 1 is no longer valid, but step 1 was completed on Line 2 and hasn't changed.

Am I doing something wrong, or is this a bug?

banana.py 
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)

Hi there,

This can take some getting used to, because it works the other way around in some other languages, but in Python .join() is called on the join string, not the list. This is an easy fix, though! You just need to switch the positions of the list and the string on that line, like this:

display_menu = ", ".join(sundaes)

is this lesson especially harder than the rest to anyone else? It made me feel very stupid for not having a single clue what was going on for step 3.
