    This is a multi-line string (used as a comment) immediately
    after the function definition. If you copy and paste an example
    run of your function (from the IDLE shell) here, doctest will
    run the function with the specified arguments and make sure that
    the output (both prints and returns) matches.
    If you use "#doctest: +ELLIPSIS" after the function call, you can
    use ellipsis (...) in your sample output to accept variable output.

    code needed to actually run the doctest!
