Boundaries between numbers and identifiers

by Serhiy Storchaka

In Python 2.5 `0or[]` was accepted by the Python parser. It became an error in 2.6 because "0o" became recognizing as an incomplete octal number. `1or[]` still is accepted. On other hand, `1if 2else 3` is accepted despites the fact that "2e" can be recognized as an incomplete floating point number. In this case the tokenizer pushes "e" back and returns "2". Shouldn't it do the same with "0o"? It is possible to make `0or[]` be parseable again. Python implementation is able to tokenize this example: $ echo '0or[]' | ./python -m tokenize 1,0-1,1: NUMBER '0' 1,1-1,3: NAME 'or' 1,3-1,4: OP '[' 1,4-1,5: OP ']' 1,5-1,6: NEWLINE '\n' 2,0-2,0: ENDMARKER '' On other hand, all these examples look weird. There is an assymmetry: `1or 2` is a valid syntax, but `1 or2` is not. It is hard to recognize visually the boundary between a number and the following identifier or keyword, especially if numbers can contain letters ("b", "e", "j", "o", "x") and underscores, and identifiers can contain digits. On both sides of the boundary can be letters, digits, and underscores. I propose to change the Python syntax by adding a requirement that there should be a whitespace or delimiter between a numeric literal and the following keyword.

About "python-porting" mail list

by Facundo Batista

Hello! This list (which I co-admin, with Georg) is getting less and less traffic as months pass by. See: https://mail.python.org/pipermail/python-porting/ The interwebs has been collecting ton of resources about porting py2 to 3 during these years. Any not-yet-answered question surely can be done in a list with more participants. Can we kill this list? Thanks! Regards, -- .

congrats on 3.5! Alas, windows 7 users are having problems installing it

by Laura Creighton

webmaster has already heard from 4 people who cannot install it. I sent them to the bug tracker or to python-list but they seem not to have gone either place. Is there some guide I should be sending them to, 'how to debug installation problems'? Laura

why is not 64-bit installer the default download link for Windows?

by Cosimo Lupo

If one goes to httWhps://www.python.org/downloads <https://www.python.org/downloads> from a Windows browser, the default download URL is for the 32-bit installer instead of the 64-bit one. I wonder why is this still the case? Shouldn't we encourage new Windows users (who may not even know the distinction between the two architectures) to use the 64-bit version of Python, since most likely they can? If this is not the correct forum for this, please let me know where I can direct my question/feature request, thanks. Cosimo -- Cosimo Lupo

3.7.2rc1 and 3.6.8rc1 cutoffs ahead, last 3.6.x bugfix release!

by Ned Deily

https://discuss.python.org/t/3-7-2rc1-and-3-6-8rc1-cutoffs-ahead-last-3-6-x… We're reaching the end of the year and it's time for another pair of Python 3 maintenance releases, 3.7.2 and 3.6.8, before we ring out 2018. Since there are still some open release blocker issues and I haven't been bugging you about them, I've moved the code cutoff for the release candidates to this coming Friday, 12-07, by the end of the day (AOE). That gives us all another 4 days to review open issues and PRs. Please give highest attention to any release blockers you have been shepherding or reviewing. Thanks! A reminder: as previously announced, 3.6.8 is planned to be the last bugfix release of the 3.6 series. Python 3.6.0 was released on 2016-12-23, so by the time 3.6.8 is released, 3.6.x will have been in bugfix mode almost exactly 2 years. When a new feature release is made and enters "bugfix" mode, our policy has long been to continue to maintain the previous bugfix branch for at least one more release and then move that branch to "security fix only" mode. 3.7.0 (and 3.6.6) was released nearly six months ago and, with the release of 3.6.8, there will have been two additional 3.6.x bugfix releases since then. So, barring any showstopper issues that might arise, the upcoming 3.6.8rc1 is your last chance to make bugfix changes for 3.6.x. Following the successful release of 3.6.8, only security fixes will be accepted for the 3.6 branch and future 3.6.x releases will be source-only and scheduled as needed; no further binary installers will be produced for 3.6. Refer to the Dev Guide sections and release PEPs linked below for more information. https://devguide.python.org/devcycle/ https://devguide.python.org/#branchstatus https://www.python.org/dev/peps/pep-0494/ https://www.python.org/dev/peps/pep-0537/ -- Ned Deily nad(a)python.org -- []

Governance vote results

by Antoine Pitrou

Hello, I think readers of this mailing-list could be interested in the vote's results, which have been published just today: https://discuss.python.org/t/python-governance-vote-december-2018-results/5… In short, PEP 8016 ("The Steering Council Model", by Nathaniel and Donald) will define how Python development operates going forward. I encourage people to read the long-form results at the URL above, since the detailed rankings provide valuable information about the committers' overall preference as well. The next step will probably be to elect the first Steering Council: https://discuss.python.org/t/organizing-the-council-elections/549 That election again will be reserved to Python committers. Regards Antoine.
