[Python Wpg] Testing for Python version

[Jason Hildebrand]

Hi Syd,

Why not simply check for the feature(s) you need?  I have seen lots of python code which takes this approach.  For example:

 def _test(verbose)
     if hasattr(doctest, 'ELLIPSIS'):
         doctest.testmod(verbose=verbose,optionflags=doctest.ELLIPSIS)
     else:
         doctest.testmod(verbose=verbose)

peace,
Jason
