eric4 web browser tutorial The purpose of this tutorial is to show, step by step, how to use eric4 to implement a little web browser with eric4, Python and Qt4's QWebKit. Qt designer is used to arrange three widgets in main window: a QLineEdit which will be used to type urls into a QPushButton to start the navigation to the url typed, and a QWebView which will render the html content. The tutorial shows how a web browser can be implemented with Python, PyQt and Qt typing just a very small amount of code. Eric4 will do all the rest of the job!

Teens, kindness and cruelty on social network sites Social media use has become so pervasive in the lives of American teens that having a presence on a social network site is almost synonymous with being online. Fully 95% of all teens ages 12-17 are now online and 80% of those online teens are users of social media sites. Many log on daily to their social network pages and these have become spaces where much of the social activity of teen life is echoed and amplified—in both good and bad ways. Python en:Exceptions - Notes You have seen how you can reuse code in your program by defining functions once. What if you wanted to reuse a number of functions in other programs that you write? As you might have guessed, the answer is modules. There are various methods of writing modules, but the simplest way is to create a file with a .py extension that contains functions and variables. Another method is to write the modules in the native language in which the Python interpreter itself was written.

The tone of life on social networking sites The tone of life on social networking sites The overall social and emotional climate of social networking sites (SNS) is a very positive one where adult users get personal rewards and satisfactions at far higher levels than they encounter anti-social people or have ill consequences from their encounters. A nationally representative phone survey of American adults finds that: 85% of SNS-using adults say that their experience on the sites is that people are mostly kind, compared with 5% who say people they observe on the sites are mostly unkind and another 5% who say their answer depends on the situation. 68% of SNS users said they had an experience that made them feel good about themselves. 61% had experiences that made them feel closer to another person. (Many said they had both experiences.) 39% of SNS-using adults say they frequently see acts of generosity by other SNS users and another 36% say they sometimes see others behaving generously and helpfully.

Singleton? We don't need no stinkin' singleton: the Borg design pattern The 'Singleton' DP is all about ensuring that just one instance of a certain class is ever created. It has a catchy name and is thus enormously popular, but it's NOT a good idea -- it displays different sorts of problems in different object-models. What we should really WANT, typically, is to let as many instances be created as necessary, BUT all with shared state. Who cares about identity -- it's state (and behavior) we care about! Package Index : Isomyr 0.1 A Python Isometric Game Engine. <><> I S O M Y R <> A Python Isometric Game Engine i-so-myr: (n) Any of one or more scenes with the same measurements in foreground and background, that have different properties and can exist in any of several game worlds for a measurable period of time. Isomyr is an isometric game engine based on Pygame, and written in Python. A fork of the Isotope game engine, it provides the framework for constructing an isometric graphics game with actors who can pick up and drop objects, jump onto plaforms, and move about in projected 3d isometric environments. Actors: used for player and monster game objects.

JythonFaq/GeneralInfo - JythonWiki JythonFaq What is Jython? Jython is the successor to JPython. The Jython project was created in accordance with the CNRI JPython 1.1.x license, in order to ensure the continued existence and development of this important piece of Python software. The intent is to manage this project with the same open policies that are serving CPython so well. Mailing lists, Subversion and all current information on the Jython project is available at SourceForge, at Note that the project is migrating over to using Mercurial and will be soon available at hg.python.org WhyJython - JythonWiki Jython, lest you do not know of it, is the most compelling weapon the Java platform has for its survival into the 21st century - SeanMcGrath Why Jython There are numerous alternative languages implemented for the Java VM. The following features help to separate Jython from the rest:

UserGuide - JythonWiki Intro For a look at the Jython internal API see the generated JavaDoc documentation. General Python Documentation Since Jython is an implementation of Python for the JVM, most of the standard Python documentation applies. Look in the following places for general information: Efficient String Concatenation in Python There is a Russian translation of this article, kindly provided by Artyom Scorecky (tonnzor). An assessment of the performance of several methods Introduction Vim as a Python IDE This project converts vim in full Python/Django editor. I have included the plugins I like best to adapt vim/gvim to my daily Python and Django project editing. In the actual configuration I have removed pylint as compiler and it uses Pyflakes. It has some issues with Linux and Mac G5 configuration but it works like a charm in Linux i386.

11.13. sqlite3 — DB-API 2.0 interface for SQLite databases — Python v2.7 documentation New in version 2.5. SQLite is a C library that provides a lightweight disk-based database that doesn’t require a separate server process and allows accessing the database using a nonstandard variant of the SQL query language. Some applications can use SQLite for internal data storage.

Understanding Python’s ‘super’ « Modern Programming World When I started programming with Python (a switch I would urge any casual utility programmer to make), I learned basic syntax. I very very quickly learned that if you’re ever wondering if there’s the proverbial “better way” to do something, then there is probably already a utility built into Python to accomplish the task. Consider the ‘super’ functionality in Python: when I first encountered this, I had no idea what it was or what it meant.
