polars.Series.str.to_date#

Series.str.to_date(format: str | None = None, *, strict: bool = True, exact: bool = True, cache: bool = True) → Series[source]#

Convert a Utf8 column into a Date column.

Parameters:

format: Format to use for conversion. Refer to the chrono crate documentation for the full specification. Example: "%Y-%m-%d". If set to None (default), the format is inferred from the data.
strict: Raise an error if any conversion fails.
exact: Require an exact format match. If False, allow the format to match anywhere in the target string.
cache: Use a cache of unique, converted dates to apply the conversion.

Examples

>>> s = pl.Series(["2020/01/01", "2020/02/01", "2020/03/01"])
