ak.sort(array, axis=-1, ascending=True, stable=True, highlevel=True, behavior=None)
  • array – Data to sort, possibly within nested lists.

  • 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.

  • ascending (bool) – If True, the first value in each sorted group will be smallest, the last value largest; if False, the order is from largest to smallest.

  • stable (bool) – If True, use a stable sorting algorithm (introsort: a hybrid of quicksort, heapsort, and insertion sort); if False, use a sorting algorithm that is not guaranteed to be stable (heapsort).

  • 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.

For example,

>>> ak.sort(ak.Array([[7, 5, 7], [], [2], [8, 2]]))
<Array [[5, 7, 7], [], [2], [2, 8]] type='4 * var * int64'>
