I am a big fan and user of python. one of the most popular ways to create quick web app in python is via using mod wsgi.

The aim of mod_wsgi is to implement a simple to use Apache module which can host any Python application which supports the Python WSGI interface.

The module would be suitable for use in hosting high performance production web sites, as well as your average self managed personal sites running on web hosting services.

There are many frameworks in python, I like web.py so here is a quick example.

First lets configure modwsgi in Ubuntu

 sudo apt-get install libapache2-mod-wsgi

 sudo a2enmod wsgi

 sudo service apache2 restart

configuration in /etc/apache2/sites-available/defaults

WSGIScriptAlias /appname /var/www/webpy-app/code.py/

 Alias /appname/static /var/www/webpy-app/static/
 AddType text/html .py

 <Directory /var/www/webpy-app/>
     Order deny,allow
     Allow from all
 </Directory> 

There is generally a handler present in most web applications for wsgi calls, here is one from web.py

import web

 urls = (
     '/.*', 'hello',
     )

 class hello:
     def GET(self):
         return "Hello, world."

 application = web.application(urls, globals()).wsgifunc() 

and that's it.Hope it helps
