ak.str.join_element_wise ------------------------ .. py:module: ak.str.join_element_wise Defined in `awkward.operations.str.akstr_join_element_wise `__ on `line 16 `__. .. py:function:: ak.str.join_element_wise(*arrays, highlevel=True, behavior=None, attrs=None) :param arrays: 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 Broadcasts and concatenates all but the last array of strings in ``arrays``; the last is used as a separator. 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.binary_join_element_wise `__. Unlike Arrow's ``binary_join_element_wise``, this function has no ``null_handling`` and ``null_replacement`` arguments. This function's behavior is like ``null_handling="emit_null"`` (Arrow's default). The other cases can be implemented with Awkward slices, :py:obj:`ak.drop_none`, and :py:obj:`ak.fill_none`. See also: :py:obj:`ak.str.join`.
