What This Book Covers
Computer System and Encoding Schemes and Number System build the theory foundation; Introduction to Problem Solving and Getting Started with Python move into actual programming, followed by Flow of Control, Functions, Strings, Lists and Tuples and Dictionaries — the Python data types Class 12 builds on directly.
