Class 12 Computer Science

Class 12 Computer Science builds from programming theory into two languages. The Samacheer Kalvi syllabus opens with function, data abstraction, scoping and algorithmic strategies, then works through Python — control structures, functions, strings and string manipulation, lists, tuples, sets and dictionaries, classes and objects — before database concepts, connecting Python with MySQL, importing C++ programs, and open source concepts. One-mark questions tend to be about what a line of code returns, which method belongs to which type, or which term names a given idea, so reading code carefully matters more than writing it. The articles below cover each chapter with worked examples and the questions that come back year after year.
