i dont understand what do i have to do?

If you're totally lost, you might want to re-watch the Splitting and Joining video.

Watch for examples in the video that handle situations very similar to the one in this challenge.

This what theyre asking for:

Use .split() to break the available string apart on the semi-colons (;). Assign this to a new variable sundaes.

First, I would research the split() function & how it works. Then you have to add the symbol into the split function that will sperate the string & put this value into a variable called sundaes.

Right, what Cindy and Steven are saying is right.

You're given this un-python friendly list, where it's one long string. We want to break it up into smaller list items so that we can use it easier. Currently, it's not so easy to work with the list and say, give the user the third sundae that we sell, or alphabetize them.

Instead of

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

We'd like it to look like:

available=["banana split", "hot fudge", "cherry", "malted", "black and white"]

Because that's a python list of 5 strings.

So we want to use the handy split() function that allows you to do just that, and we want to tell the split function to split our original long string into smaller strings every time it finds a ";". So split() will search through and do just that every time it hits ";".
