ak.is_none — Awkward Array documentation

# ak.is_none

Defined in awkward.operations.structure on line 2904.

ak.is_none(array, axis=0, highlevel=True, behavior=None)
  Parameters:

    - array – Data to check for missing values (None).

    - 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.layout.Content` subclass.

    - behavior (None or dict) – Custom `ak.behavior` for the output array, if high-level.

Returns an array whose value is True where an element of `array` is None; False otherwise (at a given `axis` depth).
