Introduction

Have you always wanted to learn how to program in Python? If the answer to that question is yes, you have begun one of the greatest adventures of this century. It is easy to learn to program since there is no specialized equipment that you need to purchase to run the programs. All you need is the right version of the software, a good computer and operating system. You can learn to program from the comfort of your own home.

Python is one of the best languages with which one can learn how to program. There are multiple reasons why, but the simplest explanation is that Python is easy to read and write. It does not take too much time to write a working code since the language has a simple syntax, which makes it easy to write the code. This book acts as a guide for a beginner.

This book provides information on how one should code when using Python and what attributes of Python can be used to make the program simple. You can never trust someone who says they know everything about programming. New versions of Python are built regularly to improve the user experience. This book provides information on different aspects of the language and will help you learn more about different structures and functions in Python.

You have to keep in mind that the more you learn about programming the better you get at it. You will learn different ways to adapt your programming style to overcome some problems. There are a few exercises that have been given in the book to help you improve on writing code. I urge you to try to write the code before you look at the solutions that have been provided in the last chapter.

I hope you enjoy the journey you are about to begin. Power up that computer and prepare yourself for a few solid hours of programming.

Chapter One: An Introduction to Python

Running Python

Python is a software that can be installed and run on multiple operating systems including Mac OS X, or OS/2, Linux, Unix and Windows. If you are running Python on GNU/Linus or Mac OS X, you may already have the software installed in the system. It is recommended to use this type of system since it already has Python set up as an integral part. The programs in this book work on every operating system.

Installing on Windows

If you are using Windows, you will need to install Python and configure certain settings correctly before you start working on the examples given in this book. To do that, you must refer to specific instructions provided for your operating system on the following Python web pages:

•  http://wiki.Python.org/moin/BeginnersGuide/Download

•  http://www.Python.org/doc/faq/windows/

•  http://docs.Python.org/dev/3.0/using/windows.html

You will first need to download the official installer. Alternative versions for AMD and Itanium machines are available at http://www.Python.org/download/. This file, which has an .msi extension, must be saved at a location that you can find easily. You can then double-click this file to start the Python installation wizard, which will take you through the installation. It is best to choose the default settings if you are unsure of the answers.

Installing on Other Systems

You may choose to install Python on other systems, if you want to take
