polars.Series.clip#

Series.clip(
lower_bound: NumericLiteral | TemporalLiteral | IntoExprColumn | None = None,
upper_bound: NumericLiteral | TemporalLiteral | IntoExprColumn | None = None,
) → Series[source]#

Set values outside the given boundaries to the boundary value.

Parameters:
lower_bound

Lower bound. Accepts expression input. Non-expression inputs are parsed as literals. If set to None (default), no lower bound is applied.

upper_bound

Upper bound. Accepts expression input. Non-expression inputs are parsed as literals. If set to None (default), no upper bound is applied.

Notes

This method only works for numeric and temporal columns. To clip other data types, consider writing a when-then-otherwise expression. See when().

Examples

Specifying both a lower and upper bound:

>>> s = pl.Series([-50, 5, 50, None])
>>> s.clip(1, 10)
shape: (4,)
Series: '' [i64]
[
        1
        5
        10
        null
]

Specifying only a single bound:

>>> s.clip(upper_bound=10)
shape: (4,)
Series: '' [i64]
[
        -50
        5
        10
        null
]
