You define states and transitions between them, then attach the machine to a model object; the library automatically creates trigger methods that move the object between states. It supports callbacks (actions executed before, after, or during transitions), conditional transitions, and wildcard source states.\n\nThe library is designed for modeling workflows, event-driven systems, and stateful processes where you need to enforce valid state changes and execute side effects when transitions occur. It's built on top of six for Python 2/3 compatibility and has a minimal dependency footprint.","worth_installing":"Yes, if you need a straightforward state machine for modeling workflows or stateful behavior. The library is stable, permissively licensed, and has low install friction. However, note that maintenance is aging (last release July 2025, no recent commits); if you require active development or frequent updates, verify that the project's pace aligns with your needs.
