01 — Fundamentals

Setup, syntax, variables, types, operators, I/O, and control flow.

How each lesson works

Every .py file follows the same theory + practice format:

THEORY — read the docstring at the top (What, Why, Key rules, When to use, Common mistakes)
PRACTICE — run the file; numbered sections walk through runnable examples
