[Python Wpg] Testing for Python version

[Sydney Weidman]

Hi, all!

I'm trying to create doctests that will work on multiple platforms, each
with different versions of Python. OSX includes version 2.3.0, which
doesn't have doctest.ELLIPSIS constant available, so I need to skip
using that constant on OSX. It seems as if the idiom for testing Python
version is sys.version_info[:3] >= (2,4,0):

import sys
import doctest

def _test(verbose)
    if sys.version_info[:3] >= (2,4,0):
        doctest.testmod(verbose=verbose,optionflags=doctest.ELLIPSIS)
    else:
        doctest.testmod(verbose=verbose)

Does this seem like the "right" way to test python version?

I can't seem to find any definitive documentation about how to do this.
