Zope is a powerful Python web application platform for rapidly and collaboratively developing complex web applications. With version 3, Zope has been rebuilt on top of a Component Architecture that combines the best ideas from modern web platforms. This new edition details all the changes and new features in Zope 3. It also makes it easier to get started with Zope, incorporating input and suggestions from Zope 3 experts and newcomers alike. In addition, the book addresses the needs of Zope 2 developers who want to use Zope 3 features as they are backported into the Zope 2 platform.

The author's computer programming started out as a hobby and became a profession very quickly. He has been a web developer for many years, having opened his own business during high school already. He started his first Zope project almost half a decade ago and has successfully used Zope in innumerable applications since. A few years ago, when the rewrite of Zope was initiated, he became a developer of Zope 3. He has been continually contributing to Zope and related projects itself since. Currently he is studying Physics at the Dresden University of Technology, while continuing the Internet business.
