Methods

A big part of programming is simply breaking down large problems into smaller and smaller instructions that can work together to create a solution. Let’s think of this using a real world example. Imagine you are playing baseball and its your turn to bat. This critical moment when you swing and hit the ball for a home run can be seen as many smaller moments that led to the big play.

First you picked up a bat. Then you took a few practices swings. Then you walked up to the plate, you readied your stance, looked at the pitcher. Finally, you took a breath and swung! Each of these small steps can be seen as methods (small chunks of instructions) that you gave to your body to get a home run.

We can look at methods another way. When you play a video game and reach a new level, there may actually be real methods that are called by the game. Perhaps the game contains a life_count method that counts how many lives you have left. Another method could tally up your current score. A third method may calculate your character's current state of health. Each of these methods would take input from your actions in the game, and go back and get information from the program to keep everything updated and accurate.
