ak.str.is_in(array, value_set, *, skip_nones=False, highlevel=True, behavior=None, attrs=None)#
  • array – Array-like data (anything ak.to_layout recognizes).

  • value_set – Array-like data (anything ak.to_layout recognizes), set of values to search for in array.

  • skip_nones (bool) – If True, None values in array are not matched against value_set; otherwise, None is considered a legal value.

  • highlevel (bool) – If True, return an ak.Array; otherwise, return a low-level ak.contents.Content subclass.

  • behavior (None or dict) – Custom ak.behavior for the output array, if high-level.

  • attrs (None or dict) – Custom attributes for the output array, if high-level.

Returns True for each string in array if it matches any pattern in value_set; otherwise, returns 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.is_in.
