This book offers Python programmers one place to look when they needhelp remembering or deciphering the syntax of this open source languageand its many powerful but scantily documented modules. Thiscomprehensive reference guide makes it easy to look up the mostfrequently needed information--not just about the Python languageitself, but also the most frequently used parts of the standard libraryand the most important third-party extensions. Ask any Python aficionado and you'll hear that Python programmers haveit all: an elegant object-oriented language with readable andmaintainable syntax, that allows for easy integration with componentsin C, C++, Java, or C#, and an enormous collection of precoded standardlibrary and third-party extension modules. Moreover, Python is easy tolearn, yet powerful enough to take on the most ambitious programmingchallenges. But what Python programmers used to lack is a concise andclear reference resource, with the appropriate measure of guidance inhow best to use Python's great power. Python in aNutshell fills this need. Python in a Nutshell, Second Edition covers morethan the language itself; it also deals with the mostfrequently used parts of the standard library, and the most popular andimportant third party extensions. Revised and expanded forPython 2.5, this book now contains the gory details of Python's newsubprocess module and breaking news about Microsoft's newIronPython project. Our "Nutshell" format fits Python perfectly bypresenting the highlights of the most important modules and functionsin its standard library, which cover over 90% of your practicalprogramming needs. This book includes: A fast-paced tutorial on the syntax of the Python language An explanation of object-oriented programming in Python Coverage of iterators, generators, exceptions, modules,packages, strings, and regular expressions A quick reference for Python's built-in types and functionsand key modules Reference material on important third-party extensions,such as Numeric and Tkinter Information about extending and embedding Python Python in a Nutshell provides a solid,no-nonsense quick reference to information that programmers rely on themost. This book will immediately earn its place in any Pythonprogrammer's library. Praise for the First Edition: "In a nutshell, Python in a Nutshell serves oneprimary goal: to act as an immediately accessible goal for the Pythonlanguage. True, you can get most of the same core information that ispresented within the covers of this volume online, but this willinvariably be broken into multiple files, and in all likelihood lackingthe examples or the exact syntax description necessary to trulyunderstand a command." --Richard Cobbett, Linux Format "O'Reilly has several good books, of which Python in aNutshell by Alex Martelli is probably the best for giving yousome idea of what Python is about and how to do useful things with it." --Jerry Pournelle, Byte Magazine

ASP in a Nutshell provides the high-quality reference documentation that web application developers really need to create effective Active Server Pages. It focuses on how features are used in a real application and highlights little-known or undocumented features.This book also includes an overview of the interaction between the latest release of Internet Information Server (version 5) and ASP 3.0, with an introduction to the IIS object model and the objects it comprises. The examples shown in this section and throughout the book are illustrated in VBScript.The main components of this book are: Active Server Pages Introduction. Brief overview of the ASP application paradigm with examples in VBScript. Also included is an introduction to Microsoft's Internet Information Server 5.0, the IIS object model, and the objects that it comprises. Object Reference. Each object is discussed in the following manner: descriptions, properties, collections, methods, events, accessory files/required DLLs, and remarks, including real-world uses, tips and tricks, and author's experience (where applicable). The objects--Application, Response, Request, Server, Session, ObjectContext, and ASPError, as well as ASP Directives, Global.ASA, and Server-Side Includes--all follow this paradigm. Component Reference. This section follows the same paradigm found in Object Reference. The discussion covers all of the additional components included with IIS, such as ActiveX Data Objects, the Ad Rotator, the Browser capabilities component, the File System Object, and more. Appendixes. Gives examples in one or two objects and components using Perl, REXX, and Python in ASP. Like other books in the "In a Nutshell" series this book offers the facts, including critical background information, in a no-nonsense manner that users will refer to again and again. It is a detailed reference that enables even experienced web developers to advance their ASP applications to new levels.

In the past when code was tight and memory scarce, it was standard practice to use two-digit storage (for example 68 for the year 1968) for date code within software. Unfortunately, when the clock rolls over at midnight on the last day of December 1999, many computers won't recognize "00" as the correct date. This Year 2000 (Y2K) dilemma may potentially render many applications and hardware ineffective, unless the code is altered. This is a global problem that will affect everybody and must be seriously addressed since time is a crucial factor. The Year 2000 situation affects the mainframe environment most heavily, but it can affect PCs as well. Any company that is running older software and hardware must pay attention to revising date code in programs, and possibly even updating software, the operating system, and even hardware. Other areas of concern are the millions of access-control, point of sale, process-control, and other peripherals that utilize date-stamping and grouping functions embedded in firmware. Year 2000 in a Nutshelladdresses three main aspects of the Year 2000 dilemma: Awareness. Covers main issues such as: compliance, costs, event-horizons, embedded dates and systems, date-stamping, timing, staffing, and benefits of Y2K conversion. Managerial. Covers considerations such as: triage (when the Y2K conversion process isn't started soon enough), legal issues, budgets, and standards. Also covers a project-plan: inventory, analysis, logistical estimates, planning and strategies, conversion, and testing and implementation. Technical. Covers: dates, Julian day, windowing, single-digit century, file and database date conversion, and PC issues. In addition, this book provides reference information on the date and time functions in those languages most likely to be affected by Year 2000 problems, including Cobol, PL/1, and Visual Basic. This section will be valuable for those programmers forced to dredge up old skills to analyze or revise code that may not be Year 2000 compliant. Because Cobol is particularly likely to be a problem, the book provides a complete Cobol quick reference. This is a valuable guide for those programmers who have been assigned the task of making the Cobol code Y2K compliant, but haven't had much experience with the Cobol language. The book also provides Visual Basic source code for a simple scanner designed to look for date and time functions that need to be altered for Y2K compliance. Although the code is written in Visual Basic, it can easily be converted into other languages. Whether you are a manager, a programmer, or even a user faced with the Year-2000 date compliance issue, this is an essential book that will help guide you through this crisis.
