New submission from Nick Coghlan <ncogh...@gmail.com>: The struct.Struct docs claim that creating and re-using a Struct object will be noticeably faster than calling the module level methods repeatedly with the same format string, as it will avoid parsing the format string multiple times: https://docs.python.org/3/library/struct.html#struct.Struct
This claim is questionable, as struct has used an internal Struct cache since at least 2.5, so if you're using less than 100 different struct layouts in any given process, the only thing you'll be saving is a string-keyed dictionary lookup. ---------- assignee: docs@python components: Documentation messages: 313468 nosy: docs@python, ncoghlan priority: normal severity: normal stage: needs patch status: open title: Mention implicit cache in struct.Struct docs type: enhancement versions: Python 3.6, Python 3.7, Python 3.8 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue33032> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
