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.

Only Find centralized, trusted content and collaborate around the technologies you use most. The inclusion of the defaults by the write() method is unfortunate; these were intended to be a way for an application to supply computed values that would be used if a specific configuration did not override them. We are also printing information about each section using items() method. to learn more about the package maintenance status. vanilla configparser maintainer for CPython and is currently configparser sports a bunch of interesting new features: full mapping protocol access (more *.ini file; but when reading it back in, it treats it as a string. This is for very quick parsing of simple configs, you lose all ability to fetch ints, bools, and other types of output without either transforming the object returned from Parser, or re-doing the parsing job accomplished by the Parser class elsewhere. This time we have added few extra keys in formatter_stdout section. Getting key with maximum value in dictionary?
