Application Integration: Configuration
Python's concept of an extensible library gives us rich access to numerous computing resources. The language provides avenues to make even more resources available. This makes Python programs particularly strong at integrating components to create sophisticated composite processing. In this chapter, we'll address the fundamentals of creating complex applications: managing configuration files, logging, and a design pattern for scripts that permits automated testing.
These new recipes are based on recipes shown earlier. Specifically, in the Using argparse to get command-line input, Using cmd for creating command-line applications, and Using the OS environment settings recipes in Chapter 6, User Inputs and Outputs, some specific techniques for creating top-level (main) application scripts were shown. In Chapter 10, Input/Output, Physical Format, and Logical Layout, we looked at filesystem input and output. In Chapter 12, Web Services...
