ak.str.join#

Defined in awkward.operations.str.akstr_join on line 21.

ak.str.join(array, separator, *, highlevel=True, behavior=None, attrs=None)#

Parameters:

array – Array-like data (anything ak.to_layout recognizes).
separator (str, bytes, or array of them to broadcast) – separator to insert between strings. If array-like, separator is broadcast against array.
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.

Concatenate the strings in array. The separator is inserted between each string. If array-like, separator is broadcast against array which permits a unique separator for each list of strings in array.

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.
