.. py:function:: ak.str.split_whitespace(array, *, max_splits=None, reverse=False, highlevel=True, behavior=None, attrs=None)


    :param array: Array-like data (anything :py:obj:`ak.to_layout` recognizes).
    :param max_splits: Maximum number of splits for each input
                   value. If None, unlimited.
    :type max_splits: None or int
    :param reverse: If True, start splitting from the end of each input
                value; otherwise, start splitting from the beginning of each
                value. This flag only has an effect if ``max_splits`` is not None.
    :type reverse: bool
    :param highlevel: If True, return an :py:obj:`ak.Array`; otherwise, return
                  a low-level :py:obj:`ak.contents.Content` subclass.
    :type highlevel: bool
    :param behavior: Custom :py:obj:`ak.behavior` for the output array, if
                 high-level.
    :type behavior: None or dict
    :param attrs: Custom attributes for the output array, if
              high-level.
    :type attrs: None or dict

Splits any string or bytestring-valued data into a list of substrings
according to any non-zero length sequence of
whitespace characters.

For strings, a split is performed for every sequence of Unicode whitespace
characters; for bytestrings, splitting is performed for sequences of ascii
whitespace characters.

The ``max_splits``, and ``reverse`` arguments are scalars; they cannot be
different for each string/bytestring in the sample.

Note: this function does not raise an error if the ``array`` does not
contain any string or bytestring data.

Requires the pyarrow library and calls
`pyarrow.compute.utf8_split_whitespace <https://arrow.apache.org/docs/python/generated/pyarrow.compute.utf8_split_whitespace.html>`__
or `pyarrow.compute.ascii_split_whitespace <https://arrow.apache.org/docs/python/generated/pyarrow.compute.ascii_split_whitespace.html>`__
on strings and bytestrings, respectively.
