polars.Series.cast

Series.cast(

dtype: PolarsDataType | type[int] | type[float] | type[str] | type[bool],

*,

strict: bool = True,

wrap_numerical: bool = False,

) → Self

Cast between data types.

Parameters:

dtype

DataType to cast to.

strict

If True invalid casts generate exceptions instead of nulls.

wrap_numerical

If True numeric casts wrap overflowing values instead of marking the cast as invalid.

Examples

>>> s = pl.Series("a", [True, False, True])
>>> s
shape: (3,)
Series: 'a' [bool]
[
    true
    false
    true
]

>>> s.cast(pl.UInt32)
shape: (3,)
Series: 'a' [u32]
[
    1
    0
