poli.core.util.batch.batch_input.batched(iterable: Iterable, chunk_size: int)

Generate batches of elements from an iterable.

If working on Python 3.12+, this function can be replaced with the built-in function batched from itertools. https://docs.python.org/3/library/itertools.html#itertools.batched

Parameters

• iterable (Iterable) – The iterable to be batched.

• chunk_size (int) – The size of each batch.

Yields

tuple – A tuple containing elements from the iterable, with each tuple having a length equal to chunk_size.

Examples

>>> numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
>>> for batch in batched(numbers, 3):
...     print(batch)
(1, 2, 3)
(4, 5, 6)
(7, 8, 9)
(10,)
