from python script to webservice

I'd like to create a very simple web service that exposes the functionality from my existing python script (attached here at the end) for use within my company... Please provide a solution and code, not links to other info.

Basically the simplest version could be this one:
INPUT: http://www.urladdress.com/mypythonwebservice/cc?region=global"e=goog
OUTPUT: price (523.07 for google stock last time I checked).

The script I want to provide as a service is:

# modules used in this function
import re
import sys
import os
import subprocess
import ystockquote

#download the file first
os.popen("curl -L http://www.bolsadesantiago.com/Theme/preciosacciones.aspx > precioacciones.aspx")
ticker = sys.argv[1]
ticker = str(ticker)
region = sys.argv[2]
region = str(region)

# This function takes as an input the name of a stock and region being traded,
# and goes to the acciones.aspx OR yahoo finance to find the price...
def ticker2price(ticker, region):
if region == "chile":
file = open("precioacciones.aspx")
stockstxt = file.read()
pattern = "NEMO="+ticker+".*right\">"
result = re.search(pattern, stockstxt)
price = stockstxt[result.end():result.end()+30]
price = price.split('<')[0]
price.replace( '.', '' ).replace( ',', '.' )
price = float( price.replace( '.', '' ).replace( ',', '.' ) )
return price

if region == "global":
return ystockquote.get_price(ticker)

price = ticker2price(ticker, region)
print price

NOW INSTEAD OF PRINT WANT THIS CODE TO BE A WEBSERVICE AS SPECIFIED ABOVE.

Please help me and provide code and final answer, not links to other resources.

Thanks!

I am sorry I missed the followup comment. On a unix or linux server you can do this like this:

Use your according package manager and install mod_python by typing the following into your shell:

#On debian/
sudo apt-get install libapache2-mod-python

#on fedora/centOS
sudo yum install mod_python

Open in new window

Debian/Ubuntu

Open /etc/apache2/sites-available/default (make sure to make backup of configuration file) and add:

#add either this if you want to use the Publisher Handler e.g. run python scripts directly
 <Directory /var/www/>
                Options Indexes FollowSymLinks MultiViews
                AllowOverride None
                Order allow,deny
                allow from all
                AddHandler mod_python .py
                PythonHandler mod_python.publisher
                PythonDebug On
        </Directory>
#or this if you want to use the PSP Handler e.g. run python inside html
 <Directory /var/www/>
                Options Indexes FollowSymLinks MultiViews
                AllowOverride None
                Order allow,deny
                allow from all
                AddHandler mod_python .psp
                PythonHandler mod_python.psp
                PythonDebug On
        </Directory>

Open in new window

After that restart apache by typing:

# if you are using standard apache installation
/etc/init.d/httpd restart
#if you are using lampp/xampp
/opt/lampp/lampp stop
/opt/lampp/lampp start

Open in new window

Fedora/CentOS
Open /etc/httpd/conf.d/python.conf (make sure to make backup of configuration file) add:

#add either this if you want to use the Publisher Handler e.g. run python scripts directly
LoadModule python_module modules/mod_python.so

<Directory /var/www/html/>
  Options Indexes FollowSymLinks MultiViews
  AllowOverride None
  Order allow,deny
  allow from all
  AddHandler mod_python .py
  PythonHandler mod_python.publisher
  PythonDebug On
</Directory>

#or this if you want to use the PSP Handler e.g. run python inside html
LoadModule python_module modules/mod_python.so

<Directory /var/www/html/>
  Options Indexes FollowSymLinks MultiViews
  AllowOverride None
  Order allow,deny
  allow from all
  AddHandler mod_python .psp
  PythonHandler mod_python.psp
  PythonDebug On
</Directory>

Open in new window

After that restart apache by typing:

# if you are using standard apache installation
/etc/init.d/httpd restart
#if you are using lampp/xampp
/opt/lampp/lampp stop
/opt/lampp/lampp start

Open in new window

If you added the the first configuration using the Publisher Handler you will be able to run files ending with *.py directly from /var/www/html/foo.py.

If you added the second configuration using PSP you can use python directly in html code called like this /var/www/html/foo.psp
