Accepted PEP 615: Support for the IANA Time Zone Database in the Standard Library
by Barry Warsaw April 21, 2020

April 21, 2020

The Python Steering Council accepts PEP 615 - Support for the IANA Time Zone Database in the Standard Library: https://www.python.org/dev/peps/pep-0615/ Congratulations Paul Ganssle! This is a fantastic, well written PEP, and we appreciate Paul’s engagement with the SC to clear up our last questions and concerns. We look forward to its availability in Python 3.9. Thank you Paul, and everyone who helped contribute to this important new module. Cheers, -Barry (on behalf of the Python Steering Council)

[RELEASE] Python 2.7.18, the end of an era
by Benjamin Peterson April 21, 2020

April 21, 2020

I'm eudaemonic to announce the immediate availability of Python 2.7.18. Python 2.7.18 is a special release. I refer, of course, to the fact that "2.7.18" is the closest any Python version number will ever approximate e, Euler's number. Simply exquisite! A less transcendent property of Python 2.7.18 is that it is the last Python 2.7 release and therefore the last Python 2 release. It's time for the CPython community to say a fond but firm farewell to Python 2. Users still on Python 2 can use e to compute the instantaneously compounding interest on their technical debt. Download this unique, commemorative Python release on python.org: https://www.python.org/downloads/release/python-2718/ Python 2.7 has been under active development since the release of Python 2.6, more than 11 years ago. Over all those years, CPython's core developers and contributors sedulously applied bug fixes to the 2.7 branch, no small task as the Python 2 and 3 branches diverged. There were large changes midway through Python 2.7's life such as PEP 466's feature backports to the ssl module and hash randomization. Traditionally, these features would never have been added to a branch in maintenance mode, but exceptions were made to keep Python 2 users secure. Thank you to CPython's community for such dedication. Python 2.7 was lucky to have the services of two generations of binary builders and operating system experts, Martin von Löwis and Steve Dower for Windows, and Ronald Oussoren and Ned Deily for macOS. The reason we provided binary Python 2.7 releases for macOS 10.9, an operating system obsoleted by Apple 4 years ago, or why the "Microsoft Visual C++ Compiler for Python 2.7" exists is the dedication of these individuals. I thank the past and present Python release managers, Barry Warsaw, Ned Deily, Georg Brandl, Larry Hastings, and Łukasz Langa for their advice and support over the years. I've learned a lot from them—like don't be the sucker who volunteers to manage the release right before a big compatibility break! Python 3 would be nowhere without the critical work of the wider community. Library maintainers followed CPython by maintaining Python 2 support for many years but also threw their weight behind the Python 3 statement (https://python3statement.org). Linux distributors chased Python 2 out of their archives. Users migrated hundreds of millions of lines of code, developed porting guides, and kept Python 2 in their brain while Python 3 gained 10 years of improvements. Finally, thank you to GvR for creating Python 0.9, 1, 2, and 3. Long live Python 3+! Signing off, Benjamin 2.7 release manager

Re: PEP 616 "String methods to remove prefixes and suffixes" accepted
by Raymond Hettinger April 20, 2020

April 20, 2020

Please consider adding underscores to the names: remove_prefix() and remove_suffix(). The latter method causes a mental hiccup when first read as removes-uffix, forcing mental backtracking to get to remove-suffix. We had a similar problem with addinfourl initially being read as add-in-four-l before mentally backtracking to add-info-url. The PEP says this alternative was considered, but I disagree with the rationale given in the PEP. The reason that "startswith" and "endswith" don't have underscores is that they aren't needed to disambiguate the text. Our rules are to add underscores and to spell-out words when it improves readability, which in this case it does. Like casing conventions, our rules and preferences for naming evolved after the early modules were created -- the older the module, the more likely that it doesn't follow modern conventions. We only have one chance to get this right (bugs can be fixed, but API choices persist for very long time). Take it from someone with experience with this particular problem. I created imap() but later regretted the naming pattern when if came to ifilter() and islice() which sometimes cause mental hiccups initially being read as if-ilter and is-lice. Raymond

PEP 616 "String methods to remove prefixes and suffixes" accepted
by Victor Stinner April 20, 2020

April 20, 2020

Hi, The Python Steering Council accepts the PEP 616 "String methods to remove prefixes and suffixes": https://www.python.org/dev/peps/pep-0616/ Congrats Dennis Sweeney! We just have one last request: we expect the documentation to explain well the difference between removeprefix()/removesuffix() and lstrip()/strip()/rstrip(), since it is the rationale of the PEP ;-) You can find the WIP implementation at: * https://github.com/python/cpython/pull/18939 * https://bugs.python.org/issue39939 Victor -- Night gathers, and now my watch begins. It shall not end until my death.

Further PEP 615 Discussion: Equality and hash of ZoneInfo
by Paul Ganssle April 20, 2020

April 20, 2020

A few weeks ago, I submitted PEP 615 to the steering council <https://github.com/python/steering-council/issues/22> for a decision. There's been a decent amount of discussion there with some very good questions. I think they are mostly resolved (though I'm happy to have other people look over the logic of some of my responses there), but Victor brought up the question of the equality and hash behavior of ZoneInfo, and while I'm leaning one way, I could easily be convinced - particularly if people have /real/ use cases that they are planning to implement that would be affected by this. I've summed up the options on the discourse thread <https://discuss.python.org/t/pep-615-support-for-the-iana-time-zone-databas…>, and would appreciate if anyone is able to give some feedback. Thanks! Paul
