As a concrete indication of usage statistics, Tom Robitaille did a survey earlier this year which showed that about 2% of respondents were running Python 2.6: http://astrofrog.github.io/blog/2015/05/09/2015-survey-results/ Astropy is planning to drop support for Python 2.6 in the next major release (1.2) which is scheduled for about 6 months from now. - Tom > > > David > > _______________________________________________ > NumPy-Discussion mailing list > NumPy-Discussion@scipy.org > https://mail.scipy.org/mailman/listinfo/numpy-discussion > >
