polars.Series.hash#

Series.hash(
seed: int = 0,
seed_1: int | None = None,
seed_2: int | None = None,
seed_3: int | None = None,
) Series[source]#

Hash the Series.

The hash value is of type UInt64.

Parameters:
seed

Random seed parameter. Defaults to 0.

seed_1

Random seed parameter. Defaults to seed if not set.

seed_2

Random seed parameter. Defaults to seed if not set.

seed_3

Random seed parameter. Defaults to seed if not set.

Notes

This implementation of hash does not guarantee stable results across different Polars versions. Its stability is only guaranteed within a single version.

Examples

>>> s = pl.Series("a", [1, 2, 3])
>>> s.hash(seed=42)
shape: (3,)
Series: 'a' [u64]
