At the time of writing this book, I was fortunate to work with an excellent team at Packt, whose contributions vastly improved the presentation of this book. Reshma Raman allowed me to provide her ideas to write a book dedicated to RESTful Web Services development with Django and Python, and I jumped into the exciting project. Aditi Gour helped me realize my vision for this book and provided many sensible suggestions regarding the text, the format, and the flow. The reader will notice her great work. It′s been great working with Reshma on another project and I can't wait to work with Reshma and Aditi again. I would like to thank my technical reviewers and proofreaders, for their thorough reviews and insightful comments. I was able to incorporate some of the knowledge and wisdom they have gained in their many years in the software development industry. This book was possible because they gave valuable feedback. The entire process of writing a book requires a huge number of lonely hours. I wouldn't be able to write an entire book without dedicating some time to play soccer against my sons, Kevin and Brandon, and my nephew, Nicolas. Of course, I never won a match. However, I did score a few goals. Of course, I'm talking about real-life soccer, but I must also add virtual soccer when the weather didn't allow us to kick a real-life ball.
