.. py:function:: ak.str.is_title(array, *, highlevel=True, behavior=None, attrs=None)


    :param array: Array-like data (anything :py:obj:`ak.to_layout` recognizes).
    :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

Replaces any string-valued data with True if the string is title-cased,
i.e. it has at least one cased character, each uppercase character follows
an uncased character, and each lowercase character follows an uppercase
character, otherwise False.

Replaces any bytestring-valued data with True if the string is
title-cased, i.e. it has at least one cased character, each uppercase
character follows an uncased character, and each lowercase character
follows an uppercase character, otherwise False.

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_is_title <https://arrow.apache.org/docs/python/generated/pyarrow.compute.utf8_is_title.html>`__
or
`pyarrow.compute.ascii_is_title <https://arrow.apache.org/docs/python/generated/pyarrow.compute.ascii_is_title.html>`__
on strings and bytestrings, respectively.
