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 the Use Guide for more.
- Parameters
- arr_or_dtypeobject
For array-like input, the
.dtype
attribute will be extracted.
- Returns
- bool
Whether the arr_or_dtype is an extension array type.
Notes
This checks whether an object implements the pandas extension array interface. In pandas, this includes:
Categorical
Sparse
Interval
Period
DatetimeArray
TimedeltaArray
Third-party libraries may implement arrays or types satisfying this interface as well.
Examples
>>> from pandas.api.types import is_extension_array_dtype >>> arr = pd.Categorical(['a', 'b']) >>> is_extension_array_dtype(arr) True >>> is_extension_array_dtype(arr.dtype) True
>>> arr = np.array(['a', 'b']) >>> is_extension_array_dtype(arr.dtype) False
