Python pd_read_parquet Beispiele

Beispiel #1

def test_pandas_parquet_roundtrip1(tmpdir):
    df = DataFrame({"a": [1, 2, 3], "b": ["a", "b", "c"]})

    filename = os.path.join(str(tmpdir), "test.pq")
    df.to_parquet(filename)

    pq_df = pd_read_parquet(filename)

    assert_frame_equal(df, pq_df)
