How to use the redisgraph.query_result.ResultSetColumnTypes.COLUMN_SCALAR function in redisgraph

def parse_records(self, raw_result_set):
        records = []
        result_set = raw_result_set[1]
        for row in result_set:
            record = []
            for idx, cell in enumerate(row):
                if self.header[idx][0] == ResultSetColumnTypes.COLUMN_SCALAR:
                    record.append(self.parse_scalar(cell))
                elif self.header[idx][0] == ResultSetColumnTypes.COLUMN_NODE:
                    record.append(self.parse_node(cell))
                elif self.header[idx][0] == ResultSetColumnTypes.COLUMN_RELATION:
                    record.append(self.parse_edge(cell))
                else:
                    print("Unknown column type.\n")
            records.append(record)

        return records
