My MotherCONTENTSCHAPTER 1INTRODUCTION TO PYTHONAfter reading this chapter, the reader will be able toUnderstand the chronology of PythonAppreciate the importance and features of PythonDiscover the areas in which Python can be usedInstall Anaconda1.1 INTRODUCTIONArt is an expression of human creative skill, hence programming is an art.

The choice of programming language is, therefore, important. This book introduces Python, which will help you to become a great artist. A. J. Perlis, who was a professor at the Purdue University, and who was the recipient of the first Turing award, statedA language that doesnt affect the way you think about programming is not worth knowing.Python is worth knowing. Learning Python will not only motivate you to do highly complex tasks in the simplest manners but will also demolish the myths of conventional programming paradigms.

It is a language which will change the way you program and hence look at a problem.Python is a strong, procedural, object-oriented, functional language crafted in the late 1980s by Guido Van Rossum. The language is named after Monty Python, a comedy group. The language is currently being used in diverse application domains. These include software development, web development, Desktop GUI development, education, and scientific applications. So, it spans almost all the facets of development. Its popularity is primarily owing to its simplicity and robustness, though there are many other factors too which are discussed in the chapters that follow.There are many third party modules for accomplishing the above tasks.

For example Django, an immensely popular Web framework dedicated to clean and fast development, is developed on Python. This, along with the support for HTML, E-mails, FTP, etc., makes it a good choice for web development.Third party libraries are also available for software development. One of the most common examples is Scions, which is used for build controls. When joined with the inbuilt features and support, Python also works miracles for GUI development and for developing mobile applications, e.g., Kivy is used for developing multi-touch applications.Python also finds its applications in scientific analysis. SciPy is used for Engineering and Mathematics, and IPython is used for parallel computing. Those of you working in statistics and machine learning would find some of these libraries extremely useful and easy to use.

SciPy provides MATLABMATLABMATLAB like features and can be used for processing multidimensional arrays. summarizes the above discussion.
