It was in the course of revising this same app that I encountered some cases where I should have liked to have had a DEFINE magic section: one whose values were only used in substitutions in the normal sections, not directly injected into them like DEFAULT. The configparser module provides the ConfigParser class and it should be imported. For format2 option, name key is not present in that section but is present in DEFAULT section hence it'll be taken from there. Once contents are written, we also verify the contents of the file. 1. My experience with this, an app that had a need before I was familiar with ConfigParser, leads me to suggest that whatever abstract elegance there would be in doing away with the magic DEFAULT section, it is in fact very convenient in practice.
