Python randomtable Beispiele

Beispiel #1

Datei: test_etl.py Projekt: shepardjma/parsons

    def test_chunk(self):

        test_table = Table(petl.randomtable(3, 499, seed=42))
        chunks = test_table.chunk(100)

        # Assert rows of each is 100
        for c in chunks[:3]:
            self.assertEqual(100, c.num_rows)

        # Assert last table is 99
        self.assertEqual(99, chunks[4].num_rows)
