I wish to thank my wife, Vidya for her constant support and encouragement. I was writing this book at an exciting and challenging time because we were expecting our second child - Nihar. My daughter Kavya also had to endure several solitary days, as her dad devoted to writing.

A big thanks to all the wonderful people at Packt Publishing - Rebecca, Fahad, Vivek and many others who helped in the creation of this book. Truly appreciate the honest reviews by Krace, Shoubhik and Jai. Sincere thanks to Anil Menon for his inputs on the 'SuperBook' storyline. Eternally grateful to Sandy for letting us use his dazzling click of a Hummingbird titled 'Alive!' as the cover photo.

I express my unending appreciation of the entire Django and Python community for being open, friendly and incredibly collaborative. Without their hard work and generosity, we would not have the great tools and knowledge that we depend on everyday.

Last but not the least, special thanks to my parents and friends who have always been there to support me.
