Does anyone know about workflow frameworks/libraries in Python?
Unfortunately it seems like most/all of the projects listed here are no longer active. Here's a new project which is currently ongoing:
Another workflow project that I saw recently was repoze.workflow, which is a state-machine based workflow engine which was inspired by plone, but is a clean re-implementation.

Not exactly sure how production ready it really is, but I do know some people that are using it.
