Config

Config is a Python module that provides a hierarchical, easy-to-use, and powerful configuration scheme. It supports mappings, sequences, cross-references between configuration parts, flexible access to Python objects, includes, simple expression evaluation, and the ability to change, save, cascade, and merge configurations. It also interfaces easily with environment variables and command-line options. The current version is 0.5.1 and it appears to be actively maintained, with the latest release in September 2021 and recent mentions in 2025-2026 as stable.
