    Harvard University (CS50)

    Artificial Intelligence

    CS50's Introduction to Artificial Intelligence with Python

    Harvard's AI course, published free as OpenCourseWare. Seven lecture topics work through search, knowledge representation, uncertainty, optimisation, machine learning, neural networks and language, with Python projects attached to each. It is explicitly a follow-on rather than a first course: the stated prerequisite is CS50x or roughly a year of Python experience, and the material assumes the learner can already write and debug their own programs.

    Programming

    CS50's Introduction to Computer Science

    Harvard's introductory computer science course, taught through eleven weeks that begin in Scratch and move into C, then Python, SQL and web development with Flask. It spends unusually long on what happens underneath a program, covering arrays, memory, pointers and data structures, before reaching higher-level languages, and ends with a self-directed final project. The course materials are free; a certificate is a separate paid option through edX.
