I just re-discovered sparta.py 0.5: RDF made easy by Mark Nottingham (mnot). He says:
the next step for sparta is to wrap Redland as well as rdflib.
Nice.
He's also got a good looking REST (get, post, delete) API in Python too called http (that link should annoy google) of which there is more about in The Whole Web in a Python Dictionary. (via Josh Sled)
