well, we are using that as a transition mechanism, trying not to support more than one Python2/Python3 version. And there are still packages where package maintainers only provide one Python3.x extension module. Yes, Ubuntu 18.10 has both 3.6 (default) and 3.7, but mainly because the time was to short to do the switch (which is now done in the Ubuntu development version). _______________________________________________ Linux-sig mailing list -- linux-sig@python.org To unsubscribe send an email to linux-sig-le...@python.org https://mail.python.org/mailman3/lists/linux-sig.python.org
