PythonEggs - The PEAK Developers' Center NOTE: If all you want to do is install a project distributed as an .egg file, head straight to the Easy Install page. EasyInstall makes installing Python code as easy as typing easy_install SomeProjectName. You don't need to read this page unless you want to know more about how eggs themselves work. "Eggs are to Pythons as Jars are to Java..." Python eggs are a way of bundling additional information with a Python project, that allows the project's dependencies to be checked and satisfied at runtime, as well as allowing projects to provide plugins for other projects. The easiest way to install and use Python eggs is to use the "Easy Install" Python package manager, which will find, download, build, and install eggs for you; all you do is tell it the name (and optionally, version) of the Python project(s) you want to use. The primary benefits of Python Eggs are: There are also other benefits that may come from having a standardized format, similar to the benefits of Java's "jar" format.

Python Twitter Tools (command-line client and IRC bot) What is it? Python Twitter Tools (PTT) includes a Twitter API, command-line tool, and IRC bot. It is developed by Mike Verdone and the Python Twitter Tools developer team. The Minimalist Twitter API for Python is a Python API for Twitter, everyone's favorite Web 2.0 Facebook-style status updater for people on the go. Why PTT is better than X? The other two Python Twitter APIs in PyPi pale in comparison to PTT because... It's minimalist. Oh neato I want it (how to install) twitter requires setuptools. After that type twitter -h to learn how to use the command-line tool, or twitterbot to learn about the Twitter IRC bot. To use the ircbot you will need the Python IRC library (python-irclib). Screenshots It's a command-line tool... oh fine, here: [mverdone@moxie2 ~]$ twitter set releases his twitter API and command-line tool for Python! Downloads You really don't need to download these as easy_install will find them automatically but if you really want the base packages...

Braintree Python Docs [1] We are unable to underwrite the following business models: icalendar 2.2 The icalendar package is a parser/generator of iCalendar files for use with Python. Changes in version 3.0 API Change Since version 3.0 the icalendar de/serialization API is unified to use only to_ical (for writing an ical string from the internal representation) and from_ical (for parsing an ical string into the internal representation). to_ical is now used instead of the methods ical, string, as_string and instead of string casting via __str__ and str. from_ical is now used instead of from_string. This change is a requirement for future Python 3 compatibility. Timezone support Timezones are now fully supported in icalendar for serialization and deserialization. Instead of our own UTC tzinfo implementation we use pytz UTC tzinfo object now. About this fork which is not a fork anymore After some thoughts we (Plone developers involved with send a suggestion to to take over maintaining of icalendar. License

Presentation: pip and virtualenv | mathematism Screencasts, diagrams, and links from my presentation for July's django-district. I put together a walkthrough of pip and virtualenv for the django-district July meeting. It was a slide-less presentation, focusing mostly on talking points and command-line walkthroughs. virtualenv virtualenv is a tool to create isolated Python environments. The Problem To illustrate the problem let’s pretend you have a Web server with two Web sites on it: and The global site-packages directory has Django 1.0.2, Pinax 0.5 and PIL 1.1.6 among other things. One day, the client for decides they’d like to take advantage of some of the new features in Django 1.1. The Solution and need the ability to have their own set of dependencies. virtualenv creates an environment that has its own installation directories and isolates itself from other virtual environments. This allows us to install a different set of dependencies for each of our sites.

virtualenvwrapper 2.8 Enhancements to virtualenv virtualenvwrapper is a set of extensions to Ian Bicking's virtualenv tool. The extensions include wrappers for creating and deleting virtual environments and otherwise managing your development workflow, making it easier to work on more than one project at a time without introducing conflicts in their dependencies. Warning: The 4.x release includes some potentially incompatible changes for extensions from 3.x. Organizes all of your virtual environments in one place.Wrappers for creating, copying and deleting environments, including user-configurable hooks.Use a single command to switch between environments.Tab completion for commands that take a virtual environment as argument.User-configurable hooks for all operations.Plugin system for more creating sharable extensions. Rich Leland has created a short screencast showing off the features of virtualenvwrapper. See the project documentation for installation and setup instructions. Supported Shells Python Versions

Toolkit - The Open Source PDF library The ReportLab Toolkit is a library for programatically creating documents in PDF format. It's a robust, flexible, time-proven, industry-strength solution. It's free, open-source software written in Python. It lets you quickly and easily create or automate complex or data-driven documents. It's in production use across the world as the trusted and proven foundation of existing enterprise solutions. The library implements three main layers: A graphics canvas API allowing you to 'draw' PDF pages and also create many of the special features of PDF files (outline entries, links and so on) A charts and widgets library for creating reusable data graphics, including many common business and financial charts A flexible page layout engine - PLATYPUS ("Page Layout and TYPography Using Scripts") - which builds documents from components like headlines, paragraphs, fonts, tables, images, and vector graphics.

python-dateutil - Labix Description The dateutil module provides powerful extensions to the standard datetime module, available in Python 2.3+. News 2011-03-24 dateutil 2.0 is out! Ported to Python 3, by Brian Jones. Features Computing of relative deltas (next month, next year, next monday, last week of month, etc); Computing of relative deltas between two given date and/or datetime objects; Computing of dates based on very flexible recurrence rules, using a superset of the iCalendar specification. Quick example Here's a snapshot, just to give an idea about the power of the package. Suppose you want to know how much time is left, in years/months/days/etc, before the next easter happening on a year with a Friday 13th in August, and you want to get today's date out of the "date" unix system command. And here's the output: Today is: 2003-10-11 Year with next Aug 13th on a Friday is: 2004 How far is the Easter of that year: relativedelta(months=+6) And the Easter of that year is: 2004-04-11 Source code and development

a crossplatform framework for creating NUI applications Tearing up the Windows Registry with python-registry Recently, I wanted to dig deep into a forensic artifact resident in the Windows Registry. To make the task more interesting, I challenged myself to use only tools native to my favorite operating system: Linux. I was quickly disappointed, however, as there are few open and cross-platform tools for Windows Registry forensics beyond Perl’s Win32::Registry. So, I wrote a tool to fill this void using Python – my favorite programming language. Python-registry is the result of this effort, and provides convenient access to Windows Registry files. Background The Windows Registry file format consists of a set of allocation units, known as HBIN blocks. For example, once a Windows Registry file has been loaded by python-registry, you can select an HBIN block, and iterate through each cell. There are few libraries in the wild that parse Windows Registry files and many fewer still that encourage interaction with the underlying structure.
