Python Prep 33: Functions Part 1 – The "Write Once, Run Anywhere" Principle

In Class 33, we stop writing repetitive code and start building our own commands! Welcome to the world of Functions. We’ll learn how to define a block of logic, give it a name, and call it whenever we need it. This is the first step toward building modular and professional programs.

What we cover today:
What is a Function? The concept of a reusable "container" for code.
The def Keyword: How to define your function properly.
The 2-Step Process:
Defining: Writing the instructions.
Calling: Executing the instructions.
The Importance of Indentation: Why the code "inside" the function must be tabbed.
Scope Basics: A quick look at how code inside a function stays separate from the rest of your script.
