ak.merge_option_of_records#

ak.merge_option_of_records(array, axis=-1, *, highlevel=True, behavior=None, attrs=None)#

Parameters:

array – Array-like data (anything ak.to_layout recognizes).
axis (int) – The dimension at which this operation is applied. The outermost dimension is 0, followed by 1, etc., and negative values count backward from the innermost: -1 is the innermost dimension, -2 is the next level up, etc.
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.

Simplifies options of records, e.g.

>>> array = ak.Array([None, {"a": 1}, {"a": 2}])

into records of options, i.e.

>>> ak.merge_option_of_records(array)
<Array [{a: None}, {a: 1}, {a: 2}] type='3 * {a: ?int64}'>
