Moreover, Python is easy to learn but powerful enough to take on the most ambitious programming challenges. But what Python programmers have lacked is one concise and clear reference resource, with the appropriate measure of guidance in how best to use Python’s great power. Now Python in a Nutshell fills this need. In the tradition of O'Reilly’s “In a Nutshell” series, this book offers Python programmers one place to look when they need help remembering or deciphering the syntax of this open source language and its many modules. This comprehensive reference guide makes it easy to look up all the most frequently needed information--not just about the Python language itself, but also the most frequently used parts of the standard library and the most important third-party extensions. Python in a Nutshell focuses on Python 2.2 (and all its point releases), currently the most stable and widespread Python release. This book includes: * A fast-paced tutorial on the syntax of the Python language itself * An explanation of object-oriented programming in Python, covering both the classic and new-style object models * Coverage of other core topics, including exceptions, modules, strings, and regular expressions * A quick reference for Python’s built-in types and functions, as well as the key modules in the Python standard library, including sys, os, time, thread, math, and socket, among many others * Reference material on important third-party extensions, such as Numeric and Tkinter * Information about extending Python and embedding it into other applications

With Ruby on Rails, powerful web applications that once took weeks or months to develop can now be produced in a matter of days. If it sounds too good to be true, it isn't. If you're like a lot of web developers, you've probably considered kicking the tires on Rails — the framework of choice for the new generation of Web 2.0 developers. Ruby on Rails: Up and Running from O'Reilly takes you out for a test drive and shows you just how fast Ruby on Rails can go. This compact guide teaches you the basics of installing and using both the Ruby scripting language and the Rails framework for the quick development of web applications. Ruby on Rails: Up and Running covers just about everything you need — from making a simple database-backed application to adding elaborate Ajaxian features and all the juicy bits in between. While Rails is praised for its simplicity and speed of development, there are still a few steps to master on the way. More advanced material helps you map data to an imperfect table, traverse complex relationships, and build custom finders. A section on working with Ajax and REST shows you how to exploit the Rails service frameworks to send emails, implement web services, and create dynamic user-centric web pages. The book also explains the essentials of logging to find performance problems and delves into other performance optimizing techniques. As new web development frameworks go, Ruby on Rails is the talk of the town. And Ruby on Rails: Up and Running can make sure you're in on the discussion.

Are you a tester who spends more time manually creating complex test data than using it? A business analyst who seemingly went to college all those years so you can spend your days copying data from reports into spreadsheets? A programmer who can't finish each day’s task without having to scan through version control system output, looking for the file you want? If so, you're wasting that computer on your desk.Показать полностьюAre you a tester who spends more time manually creating complex test data than using it?

A programmer who can't finish each day’s task without having to scan through version control system output, looking for the file you want? If so, you're wasting that computer on your desk. Offload the drudgery to where it belongs, and free yourself to do what you should be doing: thinking. All you need is a scripting language (free!), this book (cheap!), and the dedication to work through the examples and exercises. Everyday Scripting with Ruby is divided into four parts. In the first, you'll learn the basics of the Ruby scripting language. In the second, you'll see how to create scripts in a steady, controlled way using test-driven design. The third part is about finding, understanding, and using the work of others — and about preparing your scripts for others to use. The fourth part, more advanced, is about saving even more time by using application frameworks.

In this book you'll learn: * How to develop web applications quickly and easily with the Ruby on Rails framework * The basics of programming principles and Ruby syntax, so you can begin to understand what’s going on under the hood * How to implement must-have web application features, such as user accounts, data validation, sending e-mail, image uploading, and more * How to use Ajax techniques with Rails and when not to use them * How to implement other Web 2.0 features in Rails, such as tag clouds and microformats If you're a web designer or developer who thinks that the coding involved in developing dynamic web applications is too difficult, think again.Показать полностьюIn this book you'll learn: * How to develop web applications quickly and easily with the Ruby on Rails framework * The basics of programming principles and Ruby syntax, so you can begin to understand what’s going on under the hood * How to implement must-have web application features, such as user accounts, data validation, sending e-mail, image uploading, and more * How to use Ajax techniques with Rails and when not to use them * How to implement other Web 2.0 features in Rails, such as tag clouds and microformats If you're a web designer or developer who thinks that the coding involved in developing dynamic web applications is too difficult, think again. This book, and the framework it covers, is the perfect solution to your needs. Ruby on Rails provides an easy-to-use method for quickly developing web applications, simplifying potentially complicated subjects such as web architecture, JavaScript, and SQL/database creation. The simplicity of Rails belies its power, though—this technology is used by major companies such as 37Signals and Google. The book provides an introduction to Ruby on Rails with the web designer in mind. Instead of focusing on the intricate syntax of each method, the book focuses on the tasks you'll want to perform on your website and then walks you through how to implement that functionality with Rails. Design and usability are kept in mind throughout, ensuring that your site both looks and works great. The book begins by covering how to set up your computer as a Rails development environment (including the MySQL database) and then follows with an introduction to Ruby and the basics of the Rails framework. Next, you are taken through several practical examples that work together to build up a complete modern web application, covering essential and useful website features such as user login, adding and editing data, data validation, image uploading, and much more. The book even covers more-advanced Rails topics such as the Rails test suite, plug-ins and components, debugging techniques, and deploying your web applications using Capistrano.
