AppEngine allows users to create a web application in Python. Once written, the app is deployed to Google's servers where it runs and even scales automatically.
I was given the opportunity to give Google's AppEngine a shot. This page is the result.
[Edit: 2014-11-02]: This is no longer true. The AppEngine site is no more. To its credit, AppEngine ran my website for over 6 years from the code that has remained largely unchanged throughout that time.
