The authors of Learning Python show you enough essentials of the Python scripting language to enable you to begin solving problems right away, then reveal more powerful aspects of the language one at a time. This approach is sure to appeal to programmers and system administrators who have urgent problems and a preference for learning by semi-guided experimentation.

First off, Learning Python shows the relationships among Python scripts and their interpreter (in a mostly platform-neutral way). Then, the authors address the mechanics of the language itself, providing illustrations of how Python conceives of numbers, strings, and other objects as well as the operators you use to work with them. Dictionaries, lists, tuples, and other data structures specific to Python receive plenty of attention including complete examples.

Authors Mark Lutz and David Ascher build on that fundamental information in their discussions of functions and modules, which evolve into coverage of namespaces, classes, and the object-oriented aspects of Python programming. There's also information on creating graphical user interfaces (GUIs) for Python applications with Tkinter.

In addition to its careful expository prose, Learning Python includes exercises that both test your Python skills and help reveal more elusive truths about the language..

Understanding the amazing force that links some of today’s most successful companies

If you cut off a spider’s leg, it’s crippled; if you cut off its head, it dies. But if you cut off a starfish’s leg it grows a new one, and the old leg can grow into an entirely new starfish

What’s the hidden power behind the success of Wikipedia, craigslist, and Skype? What do eBay and General Electric have in common with the abolitionist and women’s rights movements? What fundamental choice put General Motors and Toyota on vastly different paths? How could winning a Supreme Court case be the biggest mistake MGM could have made?

After five years of ground-breaking research, Ori Brafman and Rod Beckstrom share some unexpected answers, gripping stories, and a tapestry of unlikely connections. The Starfish and the Spider argues that organizations fall into two categories: traditional “spiders,” which have a rigid hierarchy and top-down leadership, and revolutionary “starfish,” which rely on the power of peer relationships.

The Starfish and the Spider explores what happens when starfish take on spiders (such as the music industry vs. Napster, Kazaa, and the P2P services that followed). It reveals how established companies and institutions, from IBM to Intuit to the US government, are also learning how to incorporate starfish principles to achieve success. The book explores:
* How the Apaches fended off the powerful Spanish army for 200 years
* The power of a simple circle
* The importance of catalysts who have an uncanny ability to bring people together
* How the Internet has become a breeding ground for leaderless organizations
* How Alcoholics Anonymous has reached untold millions with only a shared ideology and without a leader

The Starfish and the Spider is the rare book that will change how you understand the world around you. BACKCOVER: Advance praise for The Starfish and the Spider
