The only place we have py3.4 in Toolforge is on the Kubernetes cluster via an old Jessie based image. We are hoping to deprecate that before July 2020. At the time I write this
there are 107 pods on the Kubernetes cluster using the python3.4 image. It is actually scarily the 2nd most popular image. Php5 is the most popular and also one we need to
deprecate.

Therefore I propose to postpone dropping Python 3.4 until that date.

Python 2 is still in all Toolforge instances too and also popular (maybe still the most popular of all)

[pywikibot/core@master] [tests] Potpone dropping python 3.4 and restore testing

https://gerrit.wikimedia.org/r/594114

@bd808: is it known which minor release of Python 3.4 is used there? The reason for askin is that Python 3.4.0 is unable for tests and the minimum Python 3.4 release which can be supported currently is 3.4.1

I think Kubernetes run mostly Flask tools, so most of them will probably not use Pywikibot.

Per @Urbanecm statistics, Python 3.4 does just 0,3 % of Pywikibot Wikimedia wikis traffic in last 30 days:

The most used 100 Pywikibot user-agent strings (56 % of all Pywikibot Wikimedia wikis traffic) does not contain any Python 3.4 at all (again in last 30 days):
