This paper discusses the differences and similarities between Python and Prolog programming languages. Python is known for its popularity, ease of use, and compatibility with scientific and machine learning programs in C. On the other hand, Prolog offers powerful reasoning capabilities, especially when combined with constraint evaluation, probabilistic reasoning, and well-founded negation. Both languages are typically written in C, dynamically typed, and utilize recursive data structures. The paper introduces Janus, a system that integrates Python and Prolog into a single process, allowing for efficient inter-language communication. Janus has been successfully used in commercial applications such as natural language processing, visual query answering, and robotic automation. The paper concludes by noting that Janus can be easily adapted to other Prologs.
