polars.Series.item

Series.item(
    index: int | None = None,
) → Any

Return the Series as a scalar, or return the element at the given index.

If no index is provided, this is equivalent to s[0], with a check that the shape is (1,). With an index, this is equivalent to s[index].

Examples

>>> s1 = pl.Series("a", [1])
>>> s1.item()
1
>>> s2 = pl.Series("a", [9, 8, 7])
>>> s2.cum_sum().item(-1)
