Summary

In Core Python Applications Programming, renowned Python expert and Google developer evangelist Wesley Chun gives intermediate-to-experienced developers all the insights they need to become expert Python developers. Writing for those moving from other languages, or upgrading from Python 2.x, Chun demonstrates best practices for making the most of Python 3.x's powerful enhancements. As with all Core Series books, this one teaches via hundreds of industrial-strength code examples, from snippets to complete sample applications - all targeted at professional developers who want to build on their existing skills. Chun presents real-world insights in a relaxed, enjoyable style that makes even complex concepts easy to understand. This edition contains brand-new chapters on programming Microsoft Office and Google App Engine. New, updated, or expanded coverage also includes the latest database and web programming techniques; the effective use of Django and other frameworks, and much more. The first edition (ISBN 9780130260369) and the second edition (ISBN 9780132269933) of this book were single volumes. Python 3 has become so involved that we have split this third edition into two volumes. This volume covers the more advanced topics which will appeal to early adopters. The other volume will be called Core Python Language Fundamentalsand will be available in the summer of 2011.
