BooleanDtype()

Extension dtype for boolean data.

Warning: BooleanDtype is considered experimental. The implementation and parts of the API may change without warning.

.. method:: None :noindex:

.. rubric:: Examples

pd.BooleanDtype() BooleanDtype

Properties

kind

A character code (one of 'biufcmMOSUV'), default 'O'

This should match the NumPy dtype used when the array is converted to an ndarray, which is probably 'O' for object if the extension type cannot be represented as a built-in NumPy type.

See Also

numpy.dtype.kind

numpy_dtype

Return an instance of our numpy dtype

type

The scalar type for the array, e.g. int

It's expected ExtensionArray[item] returns an instance of ExtensionDtype.type for scalar item, assuming that value is valid (not NA). NA values do not need to be instances of type.

Methods

__from_arrow__

__from_arrow__(array: pyarrow.Array | pyarrow.ChunkedArray) -> BooleanArray

Construct BooleanArray from pyarrow Array/ChunkedArray.

construct_array_type

construct_array_type() -> type_t[BooleanArray]

Return the array type associated with this dtype.
