Let's learn Python!

Python is a high-level programming language invented by Guido Van Rossum. It is advantageous to learn Python using the Raspberry Pi for the following reasons:

• It has a very simple syntax and hence is very easy to understand.
• It offers the flexibility of implementing ideas as a sequence of scripts. This is helpful to hobbyists to implement their ideas.
• There are Python libraries for the Raspberry Pi's GPIO. This enables easy interfacing of sensors/appliances with the Raspberry Pi.
• Python is used in a wide range of applications by technology giants such as Google. These applications range from simple robots to personal AI assistance and control modules in space.
• The Raspberry Pi has a growing fan base. This combined with the vast user base of Python means that there is no scarcity of learning resources or support for projects.

In this book, we will learn Python version 3.x. We will learn each major aspect of Python programming using a demonstrative example. Find out the awesomeness of Python by learning to do things by yourself! Keep in mind that there is Python 2.x, and it has subtle differences from Python 3.x.

If you are comfortable with the Linux command-line terminal, we recommend setting up your Raspberry Pi for remote development, as shown in Chapter 11, Tips and Tricks.
