Using Python for configuration files

Python offers a variety of ways to package application inputs and configuration files. We'll look at writing files in Python notation because it's elegant and simple.

A number of packages use assignment statements in a separate module to provide configuration parameters. The Flask project, in particular, supports this. We looked at Flask in the Using the Flask framework for RESTful APIs recipe and a number of related recipes in Chapter 12, Web Services.

In this recipe, we'll look at how we can represent configuration details in Python notation.
