I am developing a Python application as a Python2.x and Python3.0

try a preprosessor. GNU cpp handles this kind of code correct:
<test_cpp.py>
#ifdef python2
print u'foo', u'bar'
#endif
#ifdef python3
print('foo', 'bar')
#endif
<end code>
results:

...
print u'foo', u'bar'
Any other suggestions?
There's a Google Summer of Code project to create a 3to2 processor.
That would let you maintain the code in 3.x, and have it automatically
translated on demand so that it will run under 2.x (where x goes back
to at least 5, I think, but I'm not sure).
Of course, it isn't finished yet, so it won't do you any good right at
the moment :(

I found also a ready made py3to2-tool (test/develop/integrate python 3.0
code natively under robust, software-rich python 2.5 environment) at:
http://code.activestate.com/recipes/574436/
It seems so complicated that I don't dare to try before some more
experienced people has commented it.
