Pylons is a lightweight web framework emphasizing flexibility and rapid development.

Pylons

Pylons is an cross-platform and an open source web application written in . It makes extensive use of the Web Server Gateway Interface standard to promote reusability and to separate functionality into distinct modules. It is strongly influenced by Ruby on Rails: two of its main components, Routes and WebHelpers, are Python reimplementations of Rails features.

It was created by James Gardner and Ben Bangert and launched in september 2005.

At the current stable release (1.0 / May 28, 2010) it has more separation of the influence by Ruby on Rails and it can be seen in the routes module.
