TASK DESCRIPTION **Proposal** I propose to drop support for Python 3.5.0 - 3.5.2 with Pywikibot 7.0 (deployed probably in September 2021). A more important step would be dropping 3.5 completely due to further advantages (path-like objects, f-strings, variable type hints, async generators and comprehensions)[1] and pywikibot gui cannot be used with Python 3.5 due to T278743. Also a lot of packages does not support Python 3.5 with their current release.[2] Anyway Toolforge provides merely 3.5.3. Please add your remarks, expand pros and cons and maybe draw attention to it when you find a blocker. **Pros** - The end of life cycle of Python 3.5 has been reached since 30th September 2020 [3] - Our documenation recommondates Python 3.6 or higher [4] - Python 3.5.0-3.5.2 does not solve a lot of recursive imports well [5] which Python 3.5.3+ does; see T286844 <https://phabricator.wikimedia.org/T286844>. With T286403 <https://phabricator.wikimedia.org/T286403> such imports are intensively used. - Python < 3.5.2 does not provide DefaultDict for type annotations [6] - Python < 3.5.2 needs additional work for backward compatibility with async iterators (not yet used within Pywikibot but possibly in future) [7] - Python 3.5 updates cannot be used with older versions [8] - Fixes and Improvements aren't provided with older Pythons [9] - Older Python versions are still supported with Pywikibot releases marked with a tag [10][11] - L10N updates can be done by maintenance scripts for older Python versions - Pywikibot 3.5.0 - 3.5.2 aren't used very often (~ 1%), see T242157 <https://phabricator.wikimedia.org/T242157> and T266984 <https://phabricator.wikimedia.org/T266984> **Cons** - Pywikibot is not updated for older Python versions - Bugfixes are not available for older Pywikibot versions **Refs** [0] https://docs.python.org/3.6/whatsnew/3.6.html [2] [3] https://devguide.python.org/devcycle/#end-of-life-branches [4] https://doc.wikimedia.org/pywikibot/stable/index.html [5] https://ci.appveyor.com/project/Ladsgroup/pywikibot-g4xqx/builds/40034703/job/vtsbfsuih2a3h1xo [6] https://codesearch.wmcloud.org/pywikibot/?q=%5C(3%2C%205&i=nope&files=&excludeFiles=&repos= [7] https://docs.python.org/3.5/reference/datamodel.html#async-iterators [8] https://docs.python.org/3.5/whatsnew/3.5.html#asyncio [9] https://docs.python.org/3.5/whatsnew/changelog.html#python-3-5-3-release-candidate-1 [10] https://pypi.org/project/pywikibot/#history [11] https://gerrit.wikimedia.org/r/admin/repos/pywikibot/core,tags TASK DETAIL https://phabricator.wikimedia.org/T286867 EMAIL PREFERENCES https://phabricator.wikimedia.org/settings/panel/emailpreferences/ To: Xqt Cc: Aklapper, pywikibot-bugs-list, DannyS712, Rubin16, Dalba, Dvorapa, Mpaa, valhallasw, Multichill, JJMC89, atagar, Xqt, Jyoo1011, JohnsonLee01, SHEKH, Dijkstra, Khutuck, Zkhalido, Viztor, Wenyi, Tbscho, MayS, Mdupont, Altostratus, Avicennasis, mys_721tx, jayvdb, Masti, Alchimista
