Python Beginner

You’ll install Python and IDLE correctly (including adding Python to your PATH), understand when to use the interactive shell vs. script files, and write your first program. Core concepts include variables, strings, integers, floats, and booleans; printing and basic math; string concatenation and indexing; integer vs. float division; type conversion; and user input. You’ll also practice clean coding habits—comments, readable variable names, and proper indentation—and build a small triangle-area calculator to connect inputs to outputs. Along the way, you’ll learn how to lean on the official Python documentation and why that’s a better first stop than crowd-sourced answers.
