Comma Code (Using Python Language)

Say you have a list value like this: spam = [ 'apples' , 'bananas' , 'tofu', 'cats' ]

Write a function that takes a list value as an argument and returns a string will all the items separated by comma and space, with and inserted before the last item. For example, passing the previous spam list to the function would return 'apples, bananas, tofu and cats'. but your function should be able to work with any list passed to it. Be sure to test the case where an empty list [ ] is passed to your function.
