This book is about the object-oriented (OO) thought process. Although choosing the theme and title of a book are important decisions, these decisions are not at all straightforward when dealing with a highly conceptual topic. Many books deal with one level or another of programming and object orientation. Several popular books cover topics including OO analysis, OO design, OO programming, design patterns, OO data (XML), the Unified Modeling Language (UML), OO web development, OO mobile development, various OO programming languages, and many other topics related to OO programming (OOP).

Updated for both Python 3.4 and 2.7, this convenient pocket guide is the perfect on-the-job quick reference. You ll find concise, need-to-know information on Python types and statements, special method names, built-in functions and exceptions, commonly used standard library modules, and other prominent Python tools.
