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.

Using packages in your Python code

We will first have a look at the ways in which third party code and libraries can be downloaded, installed, and included in the Python scripts and application we write.

Importing modules

As we have already seen in several of the examples used so far, Python libraries (modules) are used in code by importing them using the import statement. However, so far, we have only been importing the entire modules. For example, import threading imports the entire threading module and to use, say, the Thread class, you would have to specify it as threading.Thread.

Python also allows you to import single classes, and even functions, using a slightly modified syntax, as shown next:

from threading import Thread
from time import time

This preceding code imports just the Thread class and the time function from the threading and time modules respectively. Now when you want to use either within the rest of the file, you would only need to specify either Thread or time, rather...
