Great beginning tool for Python, R, SQL – DataCamp: Data Science and AI Review

Easiest explanation for basics of a programming language—especially if you learn well by doing rather than just reading. Clearly explains capabilities and how to use them (e.g. arrays, slice, splice, math operations, basic patterns for OOP and top down design). Also impressed with the subtle humor included in some questions. Will review desktop lessons to see how they compare to popular video platforms like Pluralsight, edX, etc. in the future.
