Solve the following python programming problem given the following code:
@ staticmethod 
def get_db_method_create_connection(resource, config) : 
    def get_db_connection(db_name) : 
        conf_res = getattr (config, resource) 
        conf = { k : (getattr (conf_res, k, None) if getattr (conf_res, k, None) else config.mysql [k]) for k in config.mysql.keys () } 
        db_name_use = (getattr (conf_res, 'db_name') if getattr (conf_res, 'db_name', None) else db_name) 
        return mysql_connector.MysqlConnector (conf, db_name_use) 
return <MASK> 
    
    Given the code above, what is a proper replacement for <MASK>?
