ak.str.replace_substring_regex(array, pattern, replacement, *, max_replacements=None, highlevel=True, behavior=None, attrs=None)#
  • array – Array-like data (anything ak.to_layout recognizes).

  • pattern (str) – Regular expression pattern to look for inside input values.

  • replacement (str or bytes) – What to replace the pattern with.

  • max_replacements (None or int) – If not None and not -1, limits the maximum number of replacements per string/bytestring, counting from the left.

  • 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.

Replaces non-overlapping subsequences of any string or bytestring-valued data that match a regular expression pattern with replacement.

The pattern and replacement 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.replace_substring_regex or pyarrow.compute.replace_substring_regex on strings and bytestrings, respectively.
