It would be pretty easy to make your simple code run on both 3.x and
2.6/7. Start your file (after any docstring or initial comment) with
from __future__ import division, print_function
Use "except XyxError as e:" instead of "except XyzError, e:".

# To run on both 2.x and 3.x, put this after the __future__ import:

A Python pre-built binary is overkill for such a small function. The
reason for doing so, packaging all dependencies together, does not
apply. Any binary is limited to what machines it will run on.

A Python file, especially if designed to run on 2.6, will run on most
any recent installation.
