The recent Py2 vs Py3 survey over Christmas suggests that approx. 32% of respondents write in Python 3 (increasing on last year), 68% write in Python 2 (decreasing on last year). Py3 usage is up approx. 12% on last year's survey. For personal projects Py2 and Py3 have roughly equal popularity: http://www.randalolson.com/2015/01/30/python-usage-survey-2014/ http://www.randalolson.com/2015/01/30/python-usage-survey-20... At monthly PyDataLondon meetings I remind the audience to switch to Py3 (a few do each month) as Py2's sunset date is less than 5 years away now.

Yes, but the "survey" has a terrible bias of people who actually care enough to go and respond to such survey. It also means overrepresentation of python-dev people and so on. There is a very heavy bias towards Python 3 in such a survey (as opposed to say pypi download stats)

  Hey fijal. Agreed that the survey has a self-selecting audience, I'd also argue that they're the more forward-thinking folk rather than jobbing background users. Back in April 2013 (the last time I saw python.org download stats - where did they go?!) I wrote a blog post noting that fresh downloads of Windows Python 3.3 were greater than downloads of Windows Python 2.7, for 3 months running. Windows is useful as Python isn't bundled (unlike e.g. Linux and Mac). I presume this trend has continued but have no firm evidence either way: http://ianozsvald.com/2013/04/15/more-python-3-3-downloads-than-python-2-7-for-past-3-months/ http://ianozsvald.com/2013/04/15/more-python-3-3-downloads-t... What do the PyPI stats say?
