Things in the Python 2.x vs 3.x world aren't that bad.

See:
https://python3wos.appspot.com/ and
https://wiki.python.org/moin/PortingPythonToPy3k
http://stromberg.dnsalias.org/~strombrg/Intro-to-Python/ (writing code
to run on 2.x and 3.x)

I believe just about everything I've written over the last few years
either ran on 2.x and 3.x unmodified, or ran on 3.x alone.  If you go
the former route, you don't need to wait for your libraries to be
updated.

I usually run pylint twice for my projects (after each change, prior
to checkin), once with a 2.x interpreter, and once with a 3.x
interpreter (using
http://stromberg.dnsalias.org/svn/this-pylint/trunk/this-pylint) , but
I gather pylint has the option of running on a 2.x interpreter and
warning about anything that wouldn't work on 3.x.
