the system keeps asking me if I use .join

the system does not let me move on

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

It's asking that because of your unnecessary () around the string in your .join() usage. That's a bad habit to have in Python.

It apparently doesn't like the parentheses around the sting.

Try this instead:

display_menu = ", ".join(sundaes)

Also, it looks like you forgot the part about "Then reassign the menu variable ..." — don't forget to reassign menu with the final string.

I tried this, and it worked, you have to bring down the menu at the last, for this challenge, and could you put a bracket, for join is a question.

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