pandas.ArrowDtype

class pandas.ArrowDtype(pyarrow_dtype)

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

pyarrow_dtype

Methods

None

Returns:

ArrowDtype

See also

DataFrame.convert_dtypes

Convert columns to the best possible dtypes.

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]
