Real thinking

In this chapter we will write larger programs, see how they can be broken down and become easier to understand, what the subject of computer science is all about, and build our own AI!

Functions

In this section, we will divide code up into reusable parts we call functions.
Arguments

In this section, we are continuing with functions by introducing arguments and return values, to make them more useful.
Index

In this section, we will take lists and strings apart using indexes and slices.
Sorting

In this section, we will use Python for problem solving, remind ourselves of what an algorithm is, and sort a list.
AI

In this section, we're putting all our Python knowledge into one basket. We are creating a game with multiple turtles, where we control one and the other is chasing us. That turtle is governed by an AI, an Artificial Intelligence.

Common programs and apps that we use daily consist of tens or hundreds of thousands of lines of code. The only way to keep them organised is to break them up into functions, which also explain what that code is about.

The website you are currently on is delivered by a server, a computer whose task is to listen to the internet. When you enter a certain address or click a button, one of many functions on the server is called. Each function responds to your computer with the content of the particular chapter and section you were interested in.
