So what Python framework did you use?

web.py, the web application framework of choice for discriminating hackers. web.py is itself built upon Cheetah. The data is stored in a PostgreSQL database and served by Lighttpd.

• Yandex, a Russian traffic provider whose homepage alone receives 70 million daily page views, uses web.py for certain projects.
• http://infogami.com/ built in Python using web.py, PostgreSQL, and Lighttpd.
