What am I doing wrong?

Yeah, this one was a little confusing. I am sure the ugly way that I did it was not the best way either, but it worked.

Consider my code below.

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

sundaes = available.split(";")

menu = "Our available flavors are: {}."

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

First we make the sundaes variable which is a list of strings made up of all the words split on the ; character.

Then we make a variable named menu which is our string with the braces placeholder in it to use with the format method later.

Then we overwrite our menu variable with the string formatted (so that means what is inside the format arguement will be placed where the braces are) and that argument is the result of the join method.

Join is a little confusing for me. But I worked out that you call join on a string that you want to be between the things you are joining. In this case we are putting a commer and a space so the string ", " is what we are calling .join on and I pass in the sundaes list to that.

So the end result would be the big long string for menu which reads:

"Our available flavors are: banana split, hot fudge, cherry, malted, black and white."

Again, ugly but functional. :)
