New submission from Markus Wallerberger <markus.wallerber...@tuwien.ac.at>:
The reference implementation of itertools.product creates large temporaries, which we need to remind people of at the top of the code block. However, using generator magic, we don't need to do this and can even simplify the code in the process! Basically,we iterate over a generator of product(*seq[:-1]), and extend each of the values by every value in seq[-1]. ---------- assignee: docs@python components: Documentation messages: 410573 nosy: docs@python, mwallerb priority: normal severity: normal status: open title: itertools.product reference implementation creates temporaries type: enhancement versions: Python 3.10, Python 3.11, Python 3.7, Python 3.8, Python 3.9 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue46379> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
