The Python Function Blueprint
Functions let you name a block of logic, call it whenever you need it, and change the inputs without rewriting the code. In this video we build a suite of business calculation functions — tax, discount, order total — and learn why functions are the single most important tool for writing maintainable code.
You'll learn the exact syntax, understand parameters vs arguments, master return values, and see the difference between a function that does its own printing versus one that returns a value you can use.
