Well then:

    def mydir():
        import os.path, sys
        if __name__ == '__main__':
            filename = sys.argv[0]
        else:
            filename = __file__
        return os.path.abspath(os.path.dirname(filename))

I don't think it is all that simple, but maybe I've just got used to the
idea that files don't know (and don't need to know) their names.
