=== 3.4 Functions/Methods ===
Imagine you're building a robot that can do many different tasks, like "dance," "sing," or "clean the room." Instead of writing all the instructions for dancing every single time you want the robot to dance, you can write those instructions once and give them a name, like <code>dance()</code>. Then, whenever you want the robot to dance, you just say <code>dance()</code>, and it knows exactly what to do!

In programming, '''Functions''' (also called '''Methods''' in Object-Oriented Programming, especially when they belong to an object) are like reusable blocks of code that perform a specific task. They help you organize your program, make it easier to read, and prevent you from writing the same code over and over again.

Think of them as mini-programs within your bigger program. Each function has a job to do, and you can call on it whenever you need that job done.
