Hi I have a python code performing some computation for me.I have a html page which passes certain argumnets to a php page.This php page needs to pass on the value to the Python class and get the result back. How do I go about this??

Write a commandline-app in python, that does the work for you. Invoke that using php.
Or use something like pyphp - but I haven't used it, can't comment on its usability/support etc.

A simple yet dangerous and rather rubbish solution (possibly more of a hack than a real implementation) could be achieved by using a technique described above:
<?php echo exec('python foo.py'); ?>
I would look into pyphp though. This method has so many issues attached to it it's hardly worth bothering with. I'm with Nick when I say why on earth are you needing to call Python from within PHP as opposed to using only Python or only PHP?

I do this quite a bit:
<?php
#***** GET OUTPUT OF PYTHON PROGRAM ***** $command = "/some/directory/report.py arg1 arg2 2>&1"; $p = popen($command, 'r');

What is rubbish about that - except from the obvious cleansing of input variables that has to take place? Python has a whole module dedicated to that rubbish, called subprocess.

While I certainly prefer to use Python wherever I can, that does not mean that there aren't cases where legacy systems or other constraints make this impossible. If I have e.g. a type3-based website - "how on earth" should I replace that with Python (without wasting a lot of time)?

I don't understand how the 2 are mutually exclusive?
You can have PHP and Python bindings installed on the same Apache server, unless I'm mistaken?

Not everyone have the luxury of having mod_python installed. It depends on the host. On the other hand, mod_php will almost certainly be installed on any Apache server.

What about having to set up & maintain (which might not even possible on a cheap hoster) two configs for that - just for having a few lines of python being run? And how do you go about session-state sharing and so forth? After all the scipt might need to be access controlled based on login state.
I don't say that there aren't options to run python more direct. I argumented against a rather bold statement of Mr. alexelder:

This will spawn a Python interpreter, and not be particularly efficient. You could just as well have used CGI.

Thanks for pointing that out. I thought the warning before hand could've suggested that this implementation wasn't the best. I'll be more explicit in the future.

I'm in a bit of a similar situation. I decided to use python to solve problems where I could, in a more regimented fashion. For instance, I have a set of functions in a script, table.py. After I set up mod_python to handle requests to a single directory with python, I can call this with:
embedded in the page. This is probably pretty hackish too, but at least it doesn't spawn a new process, and I don't have to solve things that aren't related to display with php.

You mean opening a local-loop socket instead of a anonymous socket, hogging at least another apache process and then possibly spawning another process if the python-script is implemented as real CGI - not fast_cgi or python - is the better solution? I doubt that. More wasteful in all aspects, with small to any gain at all.
Unix uses pipes as IPC all the time. I fail to see why that is "rubbish".
