Not at all clear. If they're not sensitive to those nuances it's just
as likely that they're a casual developer (e.g. a student just
learning to program). Such users are unlikely to start using major 3rd
party packages like Twisted or Django, which would be completely
overwhelming to someone just learning. As shown in
http://www.comp.leeds.ac.uk/nde/papers/teachpy3.html, Python 3.0
removes quite a few warts that are likely to trip up learners.
Once they are ready (probably under the wings of some guru) to dive
deeper, they may have to learn about 2.6 and how it differs -- that's
a useful exercise by itself, but if I'm right, most learners won't
have to go there because by the time they get to that point, the 3.0
ecosystem has matured enough to support their needs.
Well, ultimately the way you want to position this is your decision, but
you haven't convinced me. My experience of casual developers suggests
that they are _extremely_ sensitive to such nuances. Library support is
a big one, but even bigger than that is the reporting of errors when
mismatched versions don't work together. Are they going to understand
that 3.0 and 2.6 are actually different languages, or are they just
going to think that something's broken when they double-click on a .pyw
file they got from some random python 2.x tutorial, with python 3 for
windows installed?
My interest is not hypothetical. I am trying to avoid hearing someone
say this to me: "Oh yeah, Python, I tried that, but it didn't work. I
use Visual Basic now and it's pretty good. It has good graphics."
This type of confusion will persist for years. It will probably be
worst at the point where both versions are enjoying equal popularity,
but at least by then all the tutorials and tools will loudly say "python
TWO" or "python THREE" on them. At least now, at the outset, it is
pretty clear what direction the confusatron's going to tilt in.
