How Can I Efficiently Chunk Iterators in Python?

Iterating over Iterators in Python: Chunking

In Python, iterators can be split into smaller manageable chunks using various methods. One such method involves using recipes from the itertools documentation.

The grouper() recipe offers a solution, although it handles incomplete chunks by filling them with a specified value, raising an exception, or ignoring them altogether.

For more precision, the batched() recipe fulfills the requirement by batching data into tuples of desired size. It preserves tuples and considers incomplete chunks.

In addition, a simplified approach that handles the last chunk appropriately is using list comprehensions. This solution applies to sequences but maintains the original sequence type.

Lastly, if working in Python 3.12 or later, itertools.batched can be utilized directly for this specific purpose. Its concise implementation clearly explains its function.
