Python, Surprise me!
Here’s a simple function which converts the third item of a list into an integer and returns it, returning -1 if the list has fewer than three entries or if the third entry fails to convert. There’s nothing mysterious or surprising going on here, but I’ll delay answering this question for a moment. For me, the real surprise about Python is that, generally, I get it right first time. Python similarly caught Eric S. Raymond by surprise . His first surprise was that it took him just 20 minutes to get used to syntactically significant whitespace.
Drupy: Drupal in Python
Frédéric Péchenard s'est exprimé sur l'action du RAID durant l'intervention engagée pour appréhender Mohamed Merah, ainsi que sur l'enquête en coursPicture the scene: you're logged into a remote server via SSH, or you've installed a new graphics card and you're left staring at the command line. You need to enter a command, but you can't remember the zillion options that go along with it. You're stuck - all you can do is consult the manual pages and pore through pages of waffling technical gobbledygook. We've all been there, and no matter how experienced you are with Linux, sometimes you need to accomplish a job quickly without sifting through masses of reading material.

Well, I have a computer architecture exam in six hours and can't be bothered, so I figured I would realize a lifelong dream of mine, and make a program that prints "Hello world!" using curve fitting techniques. Enlisting the help of a good friend with numerous mathematical papers under his belt (ostensibly because he could not afford a tighter belt), MATLAB and a longing for procrastination, we embarked on this perilous journey.
Printing "Hello world!" using curve fitting techniques
ABC is an interactive programming language and environment for personal computing, originally intended as a good replacement for BASIC. It was designed by first doing a task analysis of the programming task. ABC is easy to learn (an hour or so for someone who has already programmed), and yet easy to use.

Four Python variable binding oddities
Python has some strange variable binding semantics. Here are some examples. Oddity 1: If Python were a normal lambda language, you would expect the expression x to be equivalent to (lambda: x)() . I mean x to be a variable name here, but you would expect the equivalence to hold if x were any expression. However, there is one context in which the two are not equivalent: class scope.

Black Duck plans to integrate the SpikeSource products and services into its offerings. The SpikeForge open source projects are being migrated to other forges, and we’re encouraging members of the Developer Zone to join developers on Ohloh.net , Black Duck’s open source project directory and community. As mentioned on the Developer Zone homepage, we will be discontinuing the SpikeSource website and the Developer Zone starting January 9, 2011.Dear Reader, Pylons is a lightweight web framework built on standard Python tools that provides a robust environment for writing modern web applications. It is well known for its clean architecture and loosely coupled approach, both of which make web development fast, flexible, and easy. Pylons users have long called for a definitive guide to the framework that pulls together each of its components into one easy-to-follow manual.

Steganography made simple
As programmers, our code should be readable, not cryptic; but sometimes it’s fun to surprise , obfuscate or conceal . Wikipedia says: Steganography is the art and science of writing hidden messages in such a way that no-one apart from the sender and intended recipient even realizes there is a hidden message. By contrast, cryptography obscures the meaning of a message, but it does not conceal the fact that there is a message. Lemon juice on paper never worked for me, and (as I discovered when I tried to devise a title for an earlier post ) it’s hard work hiding a text message as a pattern within a larger text message. Sadly my hair is too fine for Histiaeus’s inspired shave-a-slave trick.
I begun programming with Python in 2002, just after the release of Python 2.2. That release was a major overhaul of the language: new-style classes were introduced, the way inheritance worked changed and the builtin super was introduced. Therefore, you may correctly say that I have worked with super right from the beginning; still, I never liked it and over the years I have discovered more and more of its dark corners.
Things to Know About Python Super
In this series of tutorials, we are going to focus on the theory and implementation of transmission models in some kind of population. In epidemiology , it is common to model the transmission of a pathogen from one person to another. In the social sciences and law, we may be interested in thinking about the way in which individuals influence each other’s opinions, ideology and actions. These two examples are different, but in many ways analogous: it is not difficult to imagine the influence that one individual has on another as being similar to the infectivity of a virus in the sense that both have the ability to change the state of an individual.

The Anatomy of a Python Project
You have a pile of Python code. You think, “this could be useful to someone else.” You want to release it as an open-source project.As Titus blogged , an interesting discussion was started over on the stdlib-sig about whether argparse should be added to the standard library , and if so how to handle/whether to deprecate getopt and optparse . Since the discussion showed rather well how people think the standard library should evolve I figured I would blog about those views and my own (assuming I don't mess up and misrepresent people =). Let's begin by examining the "extreme" views of how to evolve the standard library. One view is that it should practically not exist.
