Final part of 'sundaes' code challenge

My final task was to combine the sundaes list into a new string and join them with a (", "). Then use that string with a .format() on the existing menu variable and replace the current value of the menu variable.

My code kind of does that but when it prints the formatted menu, the menu is still in its list form. I tried it in the Python IDLE GUI shell but am still having problems.

Any help would be great, thanks.

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

You have to update the menu variable so you need to save the updated one in the variable.

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

sundaes = available.split(';')

menu = "Our available flavors are: {}"

menu = menu.format(", ".join(sundaes))

That worked, thanks a lot. I didn't realize that the string part needed to be in front of the .join method.

Yeah it does, it seems weird at first doesn't it. It's because we call the method on a string and give the method the subject as the argument.
