Hi,
Can someone let me know advantage of python 3.2 over python 2.4
Why we should go to 3.2 version and why we should not stick to 2.4
What are the modules and new features those are not available in python 2.4 added to python3.2

Here is a pretty comprehensive list:
http://docs.python.org/dev/whatsnew/index.html
One advantage to moving to 3.2 is that you'll be getting bug fixes.
Python 2.6 and earlier no longer receive bug fixes.

There are loads and loads of advantages, but many are quite small. I'd
say the big ones are:
* Bugfixes. 2.4 is really old.
* The "with" statement
* Ordered Dictionaries
* argparse module
* 0b integer syntax.
* multiprocessing module
* Class decorators
* Conditional expressions
* Sending values to generators
* Dictionary views.
* print is a function
* strings are unicode
* Things are just a little bit more consistent.
Of course, all of these except the last three and a half ones are true
for Python 2.7 as well. And if you want to migrate code to Python 3,
then you should first migrate to 2.7 anyway.

The relevant question there is if there are any modules you are using
that aren't supported by Python 3.
All important modules and functions in the standardlib are also in
Python 3 (although some have been reorganized:
http://python3porting.com/stdlib.html )
But when it comes to third-party modules you'll have to make a list of
those you use and check up if they support Python 3 or not.

As other people have said, Python 2.4 is quite old. Let me comment
rather on the issue of Python 2.7 vs. Python 3.x.
We started BIND 10 about 3.5 years ago and the wisdom at that time was
"for new projects use Python 3", so we did. It has caused us a little
pain, not so much because of difficulty with the language or missing
libraries, but rather because Python 3 was missing from a lot of
Unix distributions at that time.
Since then, Python 3 is available as a package for all major
distributions, and has started to become the default (Arch Linux
already has done this). However, if you are targeting "enterprise"
systems, then Python 2 may make more sense. These tend to stay around
for years and years, and never upgrade. Ever. (*)
Basically, I advise:
Go with the latest Python 3,
unless you have a specific need for Python 2

(*) Red Hat Enterprise Linux has a 13 year support cycle... code from
2007 will be supported until 2020! If you don't think that is
weird, consider that the Linux kernel 13 years ago was 2.2.11 and
that Python itself was at version 1.5...

I don't think this is the best forum to ask a question like that.
This list is about porting python2 programs to python3. You could try
the general python-list mailing list. You'll want to clarify your
question a bit though, as I really can't tell what it is you want to do.

The Python Tutor list is a much better place to write with this kind of
question.
http://mail.python.org/mailman/listinfo/tutor/
Join that list and ask there. You will need to break down your question
into simpler pieces:
* Will you be running your Python program on the web server or on
your computer (as a client to the web server)?
* If it is running on a client, you will simply process the HTML.
The fact that a Perl script generated the HTML probably doesn't
matter.
* If running on the server, there is probably a better approach.
Please try the tutor list.
