We would like to dedicate this book to Frank Willison, O’Reilly Editor-in-Chief and Python Champion

——Christopher A. Jones and Fred L. Drake, Jr.

Frank will be remembered in the Python community for the several great Python books that he made possible, memories of his participation in many Python conferences, and his Frankly Speaking columns. The Python world (and the world at large) won’t be the same without Frank.

——Guido van Rossum, Python creator
