pandas.api.types.is_extension_array_dtype#

pandas.api.types.is_extension_array_dtype(arr_or_dtype)[source]#

Check if an object is a pandas extension array type.

See theUse Guide for more.

Parameters:

arr_or_dtypeobject

For array-like input, the.dtype attribute willbe extracted.

Returns:

bool

Whether thearr_or_dtype is an extension array type.

Notes

This checks whether an object implements the pandas extensionarray interface. In pandas, this includes:

• Categorical

• Sparse

• Interval

• Period

• DatetimeArray

• TimedeltaArray

Third-party libraries may implement arrays or types satisfyingthis interface as well.

Examples

>>>arr=np.array(['a','b'])>>>is_extension_array_dtype(arr.dtype)False
