Where am I going wrong here?

Here's the challenge question:

Alright, let's finish making our menu. 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.

Where am I going wrong here? I'm new at this so it may be obvious, just not to me! Thanks for the help.

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

EDIT Thought I should include what the code looked like before I messed it up:

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

Hello Enzie , From the glance of your code , It look fine but Treehouse use grader so it usually need to do a bit of formatting by remove . after {} and

change format(sundaes.join(", ")) to format(', '.join(sundaes))


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

You're welcome , We are friend :)

Oh actually , It might be sound confusing but I recommend using Double Quote for String but it is up to coding preferences :)
