Webrdflib.graph.Graph.value()is the matching query method, it will return a single value for a property, optionally raising an exception if there are more. You can also add triples by combining entire graphs, see Set Operations on RDFLib Graphs. Removing Triples Similarly, triples can be removed by a call to remove(): Graph.remove((s, p, o)) WebGraph support set-theoretic operators, you can add/subtract graphs, aswell as intersection (with multiplication operator g1*g2) and xor (g1^ g2). Note that BNode IDs are kept when doing set-theoretic operations, thismay or may not be what you want.
