[issue31167] timedelta produced by datetime.__sub__ does not take Daylight Savings Time into account
New submission from Joshua Li: See my SO answer and the corresponding question for detail: https://stackoverflow.com/a/45602760/5348393 Essentially, given two datetime.datetime instances t1 and t2, the following two syntactically different lines of code should be logically equivalent, but in fact differ by plus or minus one hour on Daylight Savings Time dates because `datetime.datetime.__sub__` does not appear to take DST into account. `t1.timestamp()-t2.timestamp()` `(t1-t2).total_seconds()` I am not sure if this is by intentional design, or a behavioral bug. -- components: Library (Lib) messages: 300035 nosy: JoshuaRLi priority: normal severity: normal status: open title: timedelta produced by datetime.__sub__ does not take Daylight Savings Time into account type: behavior versions: Python 3.3, Python 3.4, Python 3.5, Python 3.6, Python 3.7 ___ Python tracker <http://bugs.python.org/issue31167> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue32913] Improve regular expression HOWTO
New submission from Joshua Li : "Python HOWTOs are documents that cover a single, specific topic, and attempt to cover it fairly completely." It would be quite helpful if the section "non-capturing-and-named-groups" in the regex HOWTO contained at least a mention and short usage example of the re.match.groupdict method, something I have found to be pythonic and useful, yet it does not appear frequently in the docs. I will be submitting a PR for this. -- assignee: docs@python components: Documentation messages: 312592 nosy: JoshuaRLi, docs@python priority: normal severity: normal status: open title: Improve regular expression HOWTO type: enhancement ___ Python tracker <https://bugs.python.org/issue32913> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
