I wrote the below code

    def _expansion_validator_impl(namespace):
        '\n                                The    validator    create    a    argument    of    a    given    type    from    a    specific    set    of    arguments    from    CLI\n                                command.\n                                :param    namespace:    The    argparse    namespace    represents    the    CLI    arguments.\n                                :return:    The    argument    of    specific    type.\n                                '
        ns = vars(namespace)
        kwargs = dict(((k, ns[k]) for k in ns if (k in set(expanded_arguments))))
        setattr(namespace, assigned_arg, model_type(**kwargs))
    return _expansion_validator_impl

What's a good function header?
