Nope, sadly they don't. If you want to know the answer to something your best best is to either ask here or to just google the name of the challenge. That will usually lead you to an older thread on here where somebody has asked for help and has received the answer to the challenge.

Anyway as for the solution, there are two accepted answers. A normal long answer and a "bonus" shortened answer that is more complex. The standard answer is this:

available = "banana split;hot fudge;cherry;malted;black and white"
sundaes = available.split(';')
menu = "Our available flavors are: {}."
# This makes it so display_menu is equal to a string with all of the items of sundaes joined together by the string ", "
# In other words it's equal to: "banana split, hot fudge, cherry, malted, black and white"
display_menu = ", ".join(sundaes) 
# This replaces the menu with one which is formatted using the contents of display_menu
menu = menu.format(display_menu)

I also added comments above the two new lines to clarify them a bit.

Here is the shortened answer if you are curious about that as well:

available = "banana split;hot fudge;cherry;malted;black and white"
sundaes = available.split(';')
# This combines all of the three previous steps into one line
# It does the same thing as the previous example it just skips creating a variable for the joined sundaes
menu = "Our available flavors are: {}.".format(", ".join(sundaes))

Awesome, that makes sense now. I've tried another example using the format you gave and it all worked :) Thanks for the lines of explanation too, really helped!

Can you please give andren a "Best Answer" so that this looks like it's already answered in the Community? Thx.
