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.
Getting ready
Python assignment statements are particularly elegant. The syntax can be simple, easy to read, and extremely flexible. If we use assignment statements, we can import an application's configuration details from a separate module. This could have a name like settings.py to show that it's focused on configuration parameters.
