ak.str.ltrim(array, characters, *, highlevel=True, behavior=None)#
  • array – Array-like data (anything ak.to_layout recognizes).

  • characters (str or bytes) – Individual characters to be trimmed from the string.

  • 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.

Removes any leading characters of characters from any string or bytestring-valued data.

If the data are strings, characters are interpreted as unordered, individual codepoints.

If the data are bytestrings, characters are interpreted as unordered, individual bytes.

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_ltrim or pyarrow.compute.ascii_ltrim on strings and bytestrings, respectively.
