python super lost on challenge split() join()?

Just can't seem to get my head round the code for task3 ? Any help explaining it would be great. Thanks :)

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

sundaes = available.split(';')

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

You have done great. This is what they are looking for in the last step.

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

What we are doing here is we are reassigning the menu value to be a new value. The new value is the exisitng vlaue modified with the string format method. That method will get your {}'s out of your string and replace it with the paramaeter you pass in. The parameter we pass in will be a string literal with a join method. The string literal in this case is ", " which is the "seperator" we will use when we call the join method. The join method takes your sundaes list in as a parameter. So the result will be a string which is all the values in that list seperated with the comman and space, and that will all be placed at the end of your menu string. :)
