Unit 4 is the technical unit of the Applied AI Classroom course — the point where students stop describing AI and start creating code similarly to the engineers who build AI. Week 1 covers algorithms: what makes a set of steps precise, finite, and unambiguous, how binary search works, how to write pseudocode, and how to draw flowcharts. Week 2 introduces Python fundamentals — variables, data types, conditionals, loops, and functions — with no prior coding experience assumed. Week 3 teaches stu
