What should I do?

I'm learning splitting and joining lists in Python. The first task asks me to split the available variable by the semicolons:

available = "banana split;hot fudge;cherry;malted;black and white"
sundaes = available.split(";")

That part worked fine. Second task was putting in the menu variable:

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

I just can't figure out the third task which is asking me to join the available list with a comma and a space, then formatting it to the menu variable.

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

Once I run the code, it tells me that task 1 is no longer passing. Any help?

The problem you are facing starts with your join command. You need to call the join command on a string, not the array.

", ".join(sundaes)

So in essence, they want you to substitute that in the output somehow (I don't know the exact challenge so I can't tell you for sure, but this should get you in the right direction).

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

Hopefully that helps.

After I add your first line of code, it gives me the same warning. "Task 1 is no longer passing." And if I add both of them, it gives the same warning, and if I add only the second line, it gives the same warning also.

1) Create a variable named sundaes that uses split

sundaes = available.split(";")

2) Assign a new menu variable to the string "Our available flavors are: {}."

menu = "Our available flavors are {}."

3) Using .format() on the menu variable, join the sundaes items with ", " and assign them to a new menu variable.

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

That should complete all of the tasks. They want you to overwrite by assignment the menu variable using the format function and the join functions.
