The way that is recommended is to use the tool 2to3 which is found in the
python tools directory I think here is the page on it.

Hi Ken,
If I have a 2.5 module that I want to use with 3.0, what do I need to do?
Thanks.

This is not true. I agree that 2.5 is the most used right now but I totally
disagree that there are no real new features. The multiprocessing is a big
one and the with statement is another big one. What I do so that it don't
interfere with other programs is install it with 2.5 they will run side by
side all you do is install it and relink the python application with
python2.5 Then when you want to run a python application in 2.6 you either
put #!/usr/bin/python2.6 in the top or you use python2.6 bla.py.
Those are not the only two big changes either they are just the two biggest
that are making a difference in some of the things I am writing. I will
also point out that I have found it runs a small bit faster on a bubble sort
running 100,000 random numbers through the loop. They are the same run of
numbers for each test and it consistently comes out a small bit faster than
2.5. It comes out even faster if you use some of the advanced looping
features.
Also the garbage collector is a bit smarter which makes for a much better
time for all.

To any beginning Python programmers, this is the version I recommend using
rather than 2.6 or 3.x. If you know what you are doing and have a
specific need to use the later versions, then go for it. Otherwise, you
will probably encounter compatibility problems with popular 3rd party
Python libraries, including py2exe -- the one that lets you create
independent executables on Windows. In my opinion, there is almost no
functionality that one loses by using 2.5 at this time. 2.6 and 3.x are
mainly a matter of syntax changes and re-organization of built-in modules
so far.
This is not a disapproval of the direction the Python language is
going -- just a reality check on what is working well at present, so
beginners can minimize headaches.
