Hi why is this wrong display_menu = ",".join(sundaes)

I'm so stuck in this section, I get errors like cannot concatenate string and list

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 = menu.format(display_menu)

I think the problem is that you are missing a space after the comma in your .join()

display_menu = ", ".join(sundaes)  # this is where you are missing a space

You could try shorten the code like this:

available = "banana split;hot fudge;cherry;malted;black and white"

sundaes = available.split(';')
menu = "Our available flavors are: {}.".format(", ".join(sundaes))
