pandas.ArrowDtype — pandas 2.3.1 documentation

class pandas.ArrowDtype(pyarrow_dtype)[source]#

An ExtensionDtype for PyArrow data types.

Warning

ArrowDtype is considered experimental. The implementation and parts of the API may change without warning.

While most dtype arguments can accept the “string” constructor, e.g. "int64[pyarrow]", ArrowDtype is useful if the data type contains parameters like pyarrow.timestamp.

Parameters:

pyarrow_dtypepa.DataType

An instance of a pyarrow.DataType.

Attributes

Methods

Returns:

ArrowDtype

Examples

>>> import pyarrow as pa
>>> pd.ArrowDtype(pa.int64())
int64[pyarrow]

Types with parameters must be constructed with ArrowDtype.

>>> pd.ArrowDtype(pa.timestamp("s", tz="America/New_York"))
timestamp[s, tz=America/New_York][pyarrow]
>>> pd.ArrowDtype(pa.list_(pa.int64()))
list<item: int64>[pyarrow]
