Preface

Programming landscape has changes significantly over the last few years. Python is making inroads into every field that has anything to do with programming. Naturally, Python programming is a skill that one has to acquire, earlier the better.
Newbies who are learning Python as their first programming language will also find the book very simple to understand. Primary credit of this goes to the Python language—it is very simple for the beginner, yet very powerful for the expert who can tap into that power.
Many people learning Python have at least a nodding acquaintance with some programming language. So they are not interested in going through the typical curve of learning the first programming language. Instead, they are looking for something that will get them off the ground quickly. They are looking for similarities and differences in a feature that they have used in other language(s). This book should help them immensely. Instead of explaining a feature with verbose text, weI have mentioned the key points about it as "KanNotes" and explained those points with the help of programs.
If you ask us to name the most important characteristic of this book, we would say simplicity. Be it the code or the text, we have tried to make it as simple as we could. As far as the code is concerned, we wanted to present simple examples that can be easily edited, compiled and run.
You will also notice that very few programming examples in this book are code fragments. We have realized that a program that actually compiles and runs, helps improve one's understanding of a subject a great deal more, than just code fragments.
Simple exercises are exceptionally useful to complete the reader's understanding of a topic. So you will find one at the end of each chapter. Please do attempt them. They will really make you battle-ready.
We have poured my best efforts into these pages. We trust you will find the book useful. We have tried to write a Python book that makes reading it as much fun as the language is. All the best and happy programming!
