Don't know what is wrong with my code. Can someone help me?

Below is my code for the 3 code challenges. I passed the first two. And I failed on the third one. The message kept telling me task 1 is no longer passing. I really don't know what is going on. Is anything wrong with my last line of code?

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

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

You're really close here! We need to do the assignment all on one line and the join statement is a little off. Take a look at the line you need for step 3:

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

We take our sundaes string which is currently split up at the semicolons. Now we join sundaes back up but this time with a comma and a space. Then we take all that and squish it in where the curly brackets are in the menu string. Hope that clarifies things!

what about the following line of code for step 3, would this do the same job as the line of code you gave out? menu.format(", ".join(sundaes))

I did tried the code you gave in step 3 and I got the following message: Bummer! Did you use .join(", ")? I don't understand, Shouldn't this be '.join(sundaes)' instead of '.join(",")' ?

I really don't know what to say here. This is my code that passes for all steps:

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

The comma and space are supposed to come before the join. If I take the code above and copy/paste it into the challenge it passes all 3 steps.

I got it. I missed a space out there- right behind the comma. The challenge is really picky. Thanks for the help!!
