ak.str.length(array, *, highlevel=True, behavior=None)#

Replaces any string-valued data with its length in Unicode characters (not its length in bytes).

Replaces any bytestring-valued data with its length of 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_length or pyarrow.compute.binary_length on strings and bytestrings, respectively.
