      Chapter 1

      Overview

      Python is an object-oriented scripting language invented by Guido van Russom in 1991. Being a general-purpose programming language, it is widely used in many applications today across various domains such as scientific computing, desktop applications, web applications, etc. It is an interpreted language, meaning there is a Python Interpreter which executes Python programs line by line as opposed to compiled languages wherein the entire program is compiled into executable code.

      One of the major advantages of Python is that it is a cross-platform language with interpreters available for every major Operating System out there; namely Windows, Linux, MAC, FreeBSD, etc. A single Python program can be executed across any platform regardless of the Operating System and the Hardware Architecture as long as a suitable interpreter is present and the program is free from platform-specific code. Another major advantage is the design philosophy that emphasizes on code readability and a syntax that enables developers to implement concepts in fewer lines of code as compared to languages like C++, Java or C#.

      Several Python implementations exist for different operating systems today. CPython is the reference implementation written C, also happens to be the most used one. Some of the other major implementations are – IronPython (for .NET and Mono framework) and Jython (written in Java).

      1.1 Potential of Python

      As of 2017, Python is in great demand and also widely used in the IT industry. Some of the applications where Python is used include Internet of Things (IoT), BigData, Cloud Computing, Machine Learning, etc. In fact, some of the devices, applications or services you use could be powered by Python to some degree. To name a few – YouTube, DropBox, Quora, BitTorrent and Yahoo Maps use Python somewhere or the other in their systems. This goes to show how incredibly useful and powerful is Python.

      Chapter 2

      Installation and Environment Setup

      There are two versions of Python in use today – Python 2 and Python 3. While Python 2 is more common, Python 3 is relatively newer. There is a fair bit of difference in both the versions with respect to syntax. This guide focuses only on Python 2. The programs demonstrated in this book have been tested on Windows 8 and shall seamlessly work on MAC OS and Linux unless specified otherwise.

      If you use MAC OS or Unix/Linux based OS, you will mostly have Python shipped along with your OS. In order to check, open the Terminal/Shell and type the following command:

      $>python

      If this command returns an error with the likes of command not found, invalid file or directory
