ConfigObj is a simple but powerful config file reader and writer: an ini file round tripper. Its main feature is that it is very easy to use, with a straightforward programmer's interface and a simple syntax for config files. It has lots of other features though:
* Nested sections (subsections), to any level * List values * Multiple line values * String interpolation (substitution) * Integrated with a powerful validation system + including automatic type checking/conversion + and allowing default values + repeated sections * All comments in the file are preserved * The order of keys/sections is preserved * Full Unicode support * Powerful unrepr mode for storing/retrieving Python data-types
