In this third part of our App Engine series, we will start writing the python code that drives our uptime dashboard. We will be using Google’s Webapp framework, which is a lightweight tool for building applications on the platform. It also comes bundled with the SDK, so we don’t need downloading or setting up a separate framework. If you are new to the series, the best starting point would be the leading article, which serves as the series’ index. You can also read the previous part, where we discussed the directory structure and file organization.
