I do this sometimes, but only if not every argument fits between the
opening parenthesis and the 80-char limit. Otherwise, I typically
indent them at the "(" level, i.e.:

    try:
        my_final_result = finalResultComputer(somelongname,
                                                                otherlongname,

[some, subexpression])
    except AttributeError, error:
        raise computeError("foo .........         bar",
                                     "<--some message" % (interpolation, args))
