Preface To Second Edition
Programming landscape has changed 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.
If you have no programming background and you are learning Python as your first programming language you will 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 its power.
If you have some acquaintance with a programming language, you need to get off the ground quickly. To do that you need to understand the similarities/differences in a feature that you have used in other language(s) and new features that Python offers. In both respects this book should help you immensely. Instead of explaining a feature with verbose text, we have mentioned the key points about it as ‘KanNotes’ and explained those points with the help of programs.
The most important characteristic of this book is its simplicity—be it the code or the text. 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 snippets.
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. If you want solutions to these exercises then take a look at our book ‘Let Us Python Solutions’ that we are stitching together right now.
The immense success of first edition of ‘Let Us Python’ has enthused us to pour our best efforts creating this second edition. Admittedly, in the first edition there were a few key places where the topic change was a bit jarring. To address this issue many chapters have been reorganized, split or combined. In addition many new chapters have been added in this edition.
We have tried to write a Python book that makes reading it as much fun as the language is. Enjoy the book and your journey into the Python world!
