This framework is a great way to add a web interface to your Python scripts. For example, if you have a Raspberry Pi reading data from a temperature sensor, you can print that value straight to a web page.

If you are familiar with Python, developing a web app on your Raspberry Pi will be a pretty simple process. Flask is a really easy framework to get started with, and it allows you to define new routes with just a couple of lines of code.
