I would like to thank my parents for everything that they have done for me. Thanks to my wife Sangita who provided valuable support at every stage of writing of this book. Thanks to my friend Souvik, sisters Priyanki and Shambhavi, and nephew Praneet and niece Aakansha for being around. Anurag you are always remembered and a source of inspiration.
I would like to thank Angel Jathanna, the Project Coordinator, for her timely input and feedback during the course of writing. I'd also like to thank Pramila Balan, the Acquisition Editor, and Chalini Snega Victor, the Lead Technical Editor, for making several helpful suggestions with regard to the book's structure, technical accuracy, and quality control. Thanks to Reshma Raman, the Author Relations Executive for getting me involved in the project.
I would also like to thank my reviewers Alejandro Rodas for providing countless suggestions to improve the code, Michael Driscoll for pointing out otherwise unnoticeable errors, Anshuman for testing out programs and pointing errors, and Ankur Aggarwal for providing suggestions for making the book more reader friendly.
Finally thanks to the Python community for being such a supportive group and to entire team at Packt Publishing, for publishing great books in the open source domain.
