i know i use correctly the split() and the join() functions but it doesn't let me pass
available = "banana split;hot fudge;cherry;malted;black and white"
sundaes = available.split(";")
menu = "Our available flavors are: {}."
display_menu = sundaes.join(", ")
menu = menu.format(display_menu)

and join
functions correctly, well the split
function is in fact correct, but the join
function is not.
The join
function is a bit counter intuitive, instead of calling it on the thing you want to join and passing in the join string like you'd expect, you actually have to do the opposite. You call the join
function on the string you want to use to join and then pass in the array as an argument. Like this:
display_menu = ", ".join(sundaes)

where the leading string
is what you're using as the glue to hold your final string together. If you switch your join around to match this format, you'll be fine :)
