But here I have another question, as a python novice is there
really any reason for me to use any particular version of
Python?
Should I start directly with the newest? What about 2.7?
In principal you should use the ‘latest’ 3. The only problem is
that a lot of libraries are not converted to 3 yet. If you need
one of those, then you have ‘no choice’ and have to use 2.7. But
I would recommend to use ‘from __future__' to make the 2.7 code
as much as possible 3 compliant.
Please define "a lot" whilst bearing in mind green against red
here https://python3wos.appspot.com/
I just started using Python again and the first ‘real’ program I
wrote I had to write with Python 2 because the needed library
(libturpial, that is not listed on your link) works only with
Python 2. A short search about which of the two to use gives
similar answers to mine. And as far as I can see in my
neighbourhood Python 2 is almost exclusively used because used
libraries are only available in Python 2.
This is not a scientifically substantiated argument, but for me
good enough to use a lot.
Have you actaully tried running libturpial with Python 3 or have you
simply taken somebody or something's word for it? I've taken code in
the past that was "only Python 2", run it thought the 2to3 fixer and
job done. Perhaps you could do the same. Perhaps you've already
tried. Again, you're the only person who actually knows.
Of-course I tried: that is why I used “had to”. The library itself and
libraries it depends on are only existing in a 2 version (at the
moment). I write code that should work in 2 and 3 both as long as 2 is
still a significant part. I call programs with python3 (even while it
is 10 to 20 percent slower) and only when that is not possible I use
Python 2. (Except to test if code also works with Python 2.)
Did you, noting that you didn't actually answer my question, and also
noting that you do ask a lot of questions yourself? So let's try again,
did you or did you not run libturpial through 2to3? If yes what went
wrong that stopped you porting it to Python 3?
You make the statement regarding Python3 "even while it is 10 to 20
percent slower". Where is your evidence to support this statement?

My fellow Pythonistas, ask not what our language can do for you, ask
