I have this code
class PerfWorkflowRunner:
    def __init__(self, perf_workflow_config: PerfWorkflowConfig, test_id: str):
        self.__parent_workflow_id = None
        self.pwc = perf_workflow_config
        self.pwc.test_id = test_id
        self.test_id = perf_workflow_config.test_id
        self.result_db: ResultDbHandler = get_result_db_handler()
        self.rdsbms_manager: BMSWorkflowManager = get_rdsbms_workflow_manager()
        self.rdsbms_params_dict = self.pwc.rdsbms_params_dict
        self.workflow_resource_retention_time = self.pwc.workflow_resource_retention_time

    @property
    def parent_workflow_id(self):
        if not self.__parent_workflow_id:
            ValueError("ERROR: cannot start the workflow, parent workflow id does not exit")
        return self.__parent_workflow_id
    
    def get_rdsbms_params_dict(self):
        return self.rdsbms_params_dict


In my another python file I just want to use the value obtained from this   
def get_rdsbms_params_dict(self):
        return self.rdsbms_params_dict
