List slice feature that allows to create sub-lists

[cameron (Cameron Simpson)]

An iterable of iterables was suggested during the discussions:

Add batching function to itertools module

I think this is a reasonable suggestion and will put it on my list to add to CPython 3.12. Prior to that, I can add a recipe to the docs, perhaps something like: def batched(iterable, n): it = iter(iterable) while (batch := list(islice(it, n))): yield batch Will put some thought into the API: Possible names are “chunked”, “batch”, and “batched”. The word “chunked” is familiar because of its use in HTTP headers and in `more-itertools (though some of that module’s name choi…
