Overview of this book

The Raspberry Pi is one of the smallest and most affordable single board computers that has taken over the world of hobby electronics and programming, and the Python programming language makes this the perfect platform to start coding with. The book will start with a brief introduction to Raspberry Pi and Python. We will direct you to the official documentation that helps you set up your Raspberry Pi with the necessary equipment such as the monitor, keyboard, mouse, power supply, and so on. It will then dive right into the basics of Python programming. Later, it will focus on other Python tasks, for instance, interfacing with hardware, GUI programming, and more. Once you get well versed with the basic programming, the book will then teach you to develop Python/Raspberry Pi applications. By the end of this book, you will be able to develop Raspberry Pi applications with Python and will have good understanding of Python programming for Raspberry Pi.

Chapter 1. Your First Steps with Python on the Pi

In this chapter, we will look at setting up the Raspbian operating system on the Raspberry Pi and have a quick look at the Python development tools that come pre-installed on it, along with looking at some basic ways in which we can execute the Python code.

The only things that are required here are:

  • A Raspberry Pi
  • A USB power source capable of delivering at least 1A
  • USB keyboard
  • USB mouse
  • TV with HDMI port
  • An SD card (or microSD card for the model B+ and Pi 2) of at least 4GB capacity
  • An SD card reader
  • A USB hub (if you wish to connect more USB devices that there are ports on the Raspberry Pi)
  • Optionally, a WiFi adapter if you want to connect the Pi to your network wirelessly (the list of supported USB WiFi adapters is available at elinux.org/RPi_USB_Wi-Fi_Adapters)
