New submission from Chris Mellon: One of the most common requests in c.l.p and #python is a way to break an iterable up into some particular size chunks. For example, "abcdef" -> "ab", "cd", "ef". It's pretty easy to write one, but there are a few subtleties to it (like if you want padding or partial results) and it's so common that having it in the stdlib would be nice.
Attached is a patch which implements itertools.chunkify. It can optionally discard, pad, or return any leftovers in the source iterable. Tests and docstrings are included, but it needs to be documented in the manual. One thing it does not do, but maybe it should, is guess what type the yielded values should have based on the input sequence - it always returns lists. Patch is against trunk, r59186. ---------- components: Library (Lib) files: chunkify.patch messages: 57861 nosy: arkanes severity: normal status: open title: itertools should grow chunkify type: behavior versions: Python 2.6 Added file: http://bugs.python.org/file8811/chunkify.patch __________________________________ Tracker <[EMAIL PROTECTED]> <http://bugs.python.org/issue1502> __________________________________
