> - There is also datalog, with pydatalog it's python equivalent. Datalog is a strict subset of Prolog that guarantees termination (over finite sets), i.e., it's not turing-complete. This makes it more suitable for knowledge representation tasks than general programming. pydatalog is a specific implementation of a datalog reasoner.
