That's almost what I do, except that I put the terminating container
character on its own line to simplify adding and deleting arguments::

    try:
        my_final_result = finalResultComputer(
            arg1_from_abunch_of_args,
            args_should_align_properly,
            [so, what, if, they, re, compound],
            )
    except AttributeError, error:
        raise computeError(
            "foo .........         bar"
            "<--All message text lines should start here."
            % (String, interpolation, argument, list, as, well)
            )

This practice comes more from lists/dicts; I simply generalize it to
arguments.  You'll also notice that similarly I put a trailing comma on
the last argument.
