* * Python Essential Reference, 4th Edition * * by David Beazley I'm pleased to announce the release of the Python Essential Reference, 4th edition, soon to be appearing at a bookstore near you. More than a year in development, this edition covers Python 2.6, Python 3, and a wide variety of new library modules. Notable new features include - Greatly expanded coverage of advanced features such as generators, coroutines, context managers, decorators, metaclasses, and more. - Detailed coverage of concurrent programming including threads, the multiprocessing library, and coroutines. - A new chapter on testing, debugging, profiling, and performance optimization. - Completely revised examples and code samples appearing throughout the text. - New coverage of the database API, WSGI, ctypes, and other essential library modules. - Detailed information on Python 3 including compatibility notes, migration strategies, notable new features, and use of the 2to3 tool. If you liked previous editions of the Essential Reference, I think you will be pleased--this may be the best edition yet. Cheers, Dave
