Bug?
by Gilles Feyrit Jan. 10, 2018

Jan. 10, 2018

Hi, In: https://docs.python.org/3/library/re.html#regular-expression-syntax at: \WMatches any character which is not a word character. This is the opposite of \w. If the ASCII <https://docs.python.org/3/library/re.html#re.ASCII> flag is used this becomes the equivalent of [^a-zA-Z0-9_] (but the flag affects the entire regular expression, so in such cases using an explicit [^a-zA-Z0-9_] may be a better choice). If the LOCALE <https://docs.python.org/3/library/re.html#re.LOCALE> flag is used, matches characters considered alphanumeric in the current locale and the underscore. shouldn't it be instead: \WMatches any character which is not a word character. This is the opposite of \w. If the ASCII <https://docs.python.org/3/library/re.html#re.ASCII> flag is used this becomes the equivalent of [^a-zA-Z0-9_] (but the flag affects the entire regular expression, so in such cases using an explicit [^a-zA-Z0-9_] may be a better choice). If the LOCALE <https://docs.python.org/3/library/re.html#re.LOCALE> flag is used, matches characters not considered alphanumeric in the current locale and the underscore. ? Thanks.

[issue11260] smtpd-as-a-script feature should be documented and should use argparse
by Xavier Morel Jan. 10, 2018

Jan. 10, 2018

New submission from Xavier Morel <xavier.morel(a)masklinn.net>: argparse has been merged to the standard library in 3.2, and (tell me if I'm wrong) would therefore be the "best-practices" way to parse command-line arguments. Numerous stdlib modules can be used as scripts, but they tend to have ad-hoc documentation (if they are at all documented) and arguments parsing (using any of the 4 available methods in Python: straight from sys.argv, getopt, optparse and argparse). I picked smtpd as a first shot since it does something useful (SMTP proxy) and has a pretty good (if ad-hoc) command-line documentation. smtpd is currently using getopt for its options parsing and the argument parsing is very cleanly factored: the port only had to replace the implementation of the `parseargs` function (and add and remove some helpers). * The port keeps the existing arguments semantics (including the mandatory host:port syntax for the local and remote specs if overridden) * The port tries to maintain the old error messages, but due to the way argparse works (or the way I used it for the specs) the parity is not perfect when providing incorrect specs * The CLI help uses argparse's formatting, and the documentation for the local and remote specs was set on these arguments rather than as an epilog. The version string was also removed from the help screen * Because they are set by argparse's arguments validation, the status codes on incorrect arguments are slightly different: - running smtpd.py as a regular user without the `--nosetuid` flag still exits with status 1 - providing incorrect spec formats (missing or non-int port) or providing too many positional arguments (3 or more) now exits with status 2 (formerly 1) ---------- assignee: docs@python components: Documentation, Library (Lib) files: smtpd-to-argparse.diff keywords: patch messages: 128917 nosy: barry, docs@python, xmorel priority: normal severity: normal status: open title: smtpd-as-a-script feature should be documented and should use argparse versions: Python 3.3 Added file: http://bugs.python.org/file20812/smtpd-to-argparse.diff _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue11260> _______________________________________

[issue32374] Document that m_traverse for multi-phase initialized modules can be called with m_state=NULL
by Marcel Plch Jan. 9, 2018

Marcel Plch <gmarcel.plch(a)gmail.com> added the comment: I have created a PR at https://github.com/python/cpython/pull/5140 It contains documentation, plus, in --with-pydebug mode, it calls m_traverse to catch easy cases of not handling the m_state==NULL case early. ---------- _______________________________________ Python tracker <report(a)bugs.python.org> <https://bugs.python.org/issue32374> _______________________________________

DE-buging I LOVE LOU!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
by 이재하 Jan. 9, 2018

Jan. 9, 2018

Hello,my name is Jaeha Lee,and I'm live in Korea. I'm student(14) and like programming VERY VERY MUCH!!!! Of course, I'm writing this e-mail for tell you about the bug in python. it is very small and small. but please fixed it(im so hard to make my school task TT) ammm..... first "5**5**5" [ 5^5^5 ](it's not string.)This expression has the original value of 298023223876953125(3125*5), but appears as(it is little big ^^;;;;;LOL) 1911012597945477520356404559703964599198437621363257303216452829794868625762453622180176732249405676428193600787207138370723553054463561539464011853484937927195145945055082327492216058489129109451899599486861995431476669380130371761635925944797461642250823164909672857121717081232327904818172683275101127467823174109858886837085.....................................4394218232191357223054066715373374248543645663782045701654593218154053548393614250664498585403307466468541890148134347714650315037954175778622811776585876941680908203125 his means not 3125*5 but 5*3125 it means a^a^a=>a^(a^a) not (a^a)^a so, please debuging it. thank you... last, The Zen of Python, by Tim Peters Beautiful is better than ugly. Explicit is better than implicit. Simple is better than complex. Complex is better than complicated. Flat is better than nested. Sparse is better than dense. Readability counts. Special cases aren't special enough to break the rules. Although practicality beats purity. Errors should never pass silently. Unless explicitly silenced. In the face of ambiguity, refuse the temptation to guess. There should be one-- and preferably only one --obvious way to do it. Although that way may not be obvious at first unless you're Dutch. Now is better than never. Although never is often better than *right* now. If the implementation is hard to explain, it's a bad idea. If the implementation is easy to explain, it may be a good idea. Namespaces are one honking great idea -- let's do more of those! . . . I LOVE YOU!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

[issue32500] PySequence_Length() raises TypeError on dict type
by Serhiy Storchaka Jan. 6, 2018

Jan. 6, 2018

Serhiy Storchaka <storchaka+cpython(a)gmail.com> added the comment: Note that many other PySequence_* functions support only sequences. For example PySequence_Count(o1, o2) is the equivalent of the Python expression o1 + o2 only if o1 is a sequence. If pass integer objects to PySequence_Count() it will return an error. I would remove "do not" from the documentation. Or even the whole "For objects that do not provide sequence protocol" since this is implied. ---------- _______________________________________ Python tracker <report(a)bugs.python.org> <https://bugs.python.org/issue32500> _______________________________________
