Pyke introduces a form of Logic Programming (inspired by Prolog) to the Python community by providing a knowledge-based inference engine (expert system) written in 100% Python. Unlike Prolog, Pyke integrates with Python allowing you to invoke Pyke from Python and intermingle Python statements and expressions within your expert system rules.

Matita is an experimental, interactive theorem prover under development at the Computer Science Department of the University of Bologna. Matita is based on the Calculus of (Co)Inductive Constructions, and is compatible, at some extent, with Coq. It is a reasonably small and simple application, whose architectural and software complexity is meant to be mastered by students, providing a tool particularly suited for testing innovative ideas and solutions.
