Here're slides from a presentation about writing code that runs on 2.x and
3.x: http://stromberg.dnsalias.org/~dstromberg/Intro-to-Python/

And in case you still want a preprocessor for Python (you likely don't need
one this time), here's an example of doing this using the venerable m4:
https://pypi.python.org/pypi/red-black-tree-mod .  Note the many comments
added to keep line numbers consistent.
