I have this code in A.py file
class __BasePerfWorkflowService:
    """Base class for Perf workflows"""

    def __init__(
        self,
        name: str,

        **kwargs,
    ):
        """

        self.__engine = None
        self.__workflow_type = None

        self.__workflow_prefix = workflow_prefix
        self.__user_config = copy.deepcopy(user_config)

        self._set_workflow_params(workflow_config)

        self.__db_instance_size = get_instance_size(self.workflow_config["config"])
        self.__workflow_user = kwargs.get("workflow_user", None)

        """Returns sidekick params dict along with con information. None if sidekick is not passed through

        if not self.is_sidekick_enabled:
            return None

        workflow_config = self.rdsbms_params_dict()



def rdsbms_params_dict(self):
        """Returns params dict."""
        return namespace_to_dict(self.workflow_params.config)

Now in B.py file I want to use the value obtained from this code from A.py
workflow_config = self.rdsbms_params_dict()

How to import and use in B.py
