Chapter 1 Getting Acquainted with Python Python is an open source, high-level programming language developed by Guido van Rossum in the late 1980s and presently administered by Python Software Foundation. It came from the ABC language that he helped create early on in his career.

Python is a powerful language that you can use to create games, write GUIs, and develop web applications. It is a high-level language. Reading and writing codes in Python is much like reading and writing regular English statements. Because they are not written in machine-readable language, Python programs need to be processed before machines can run them. Python is an interpreted language. This means that every time a program is run, its interpreter runs through the code and translates it into machine-readable byte code.

Python is an object-oriented language that allows users to manage and control data structures or objects to create and run programs. Everything in Python is, in fact, first class. All objects, data types, functions, methods, and classes take equal position in Python. Programming languages are created to satisfy the needs of programmers and users for an effective tool to develop applications that impact lives, lifestyles, economy, and society. They help make lives better by increasing productivity, enhancing communication, and improving efficiency. Languages die and become obsolete when they fail to live up to expectations and are replaced and superseded by languages that are more powerful.

Python is a programming language that has stood the test of time and has remained relevant across industries and businesses and among programmers, and individual users. It is a living, thriving, and highly useful language that is highly recommended as a first programming language for those who want to dive into and experience programming. Advantages of Using Python Here are reasons why you would prefer to learn and use Python over other high level languages: Readability Python programs use clear, simple, and concise instructions that are easy to read even by those who have no substantial programming background. Programs written in Python are, therefore, easier to maintain, debug, or enhance. Higher productivity Codes used in Python are considerably shorter, simpler, and less verbose than other high-level programming languages such as Java and C++. In addition, it has well-designed built-in features and standard library as well as access to third party modules and source libraries.

These features make programming in Python more efficient. Less learning time Python is relatively easy to learn. Many find Python a good first language for learning programming because it uses simple syntax and shorter codes. Runs across different platforms Python works on Windows, Linux/UNIX, Mac OS X, other operating systems and small-form devices. It also runs on microcontrollers used in appliances, toys, remote controls, embedded devices, and other similar devices.
Chapter 2 Installing Python Installing Python in Windows To install Python, you must first download the installation package of your preferred version from this link: https://www.python.org/downloads/ On this page, you will be asked to choose between the two latest versions for Python 2 and 3: Python 3.5.1 and Python 2.7.11.

Alternatively, if you are looking for a specific release, you can scroll down the page to find download links for earlier versions. You would normally opt to download the latest version, which is Python 3.5.1. This was released on December 7, 2015. However, you may opt for the latest version of Python 2, 2.7.11. Your preferences will usually depend on which version will be most usable for your project. While Python 3 is the present and future of the language, issues such as third party utility or compatibility may require you to download Python 2.

Installing Python in Mac If youre using a Mac, you can download the installation package from this link: https://www.python.org/downloads/mac-osx/ Running the Installation file: Once youre finished with the download, you can proceed to installation by clicking on the downloaded .exe file. Standard installation will include IDLE, pip, and documentation.
Chapter 3 Interacting with Python Python is a flexible and dynamic language that you can use in different ways. You can use it interactively when you simply want to test a code or a statement on a line-by-line basis or when youre exploring its features. You can use it in script mode when you want to interpret an entire file of statements or application program. To use Python interactively, you can use either the Command Line window or the IDLE Development Environment.
