It is crucial to have sound knowledge of programming languages, to understand or build artificial intelligence systems. Some of the most recommended programming languages for artificial intelligence are – firstly, Python. Python is the most widely used language for AI and specialized fields like machine learning, NLP, deep learning, neural networks, etc. Next comes R, which can be extensively used in data visualization, data science, machine learning, neural networks, etc. Apart from these, knowledge of C++, Java, Prolog, and LISP is also helpful for learning AI.
