boodebr is a collection of Python modules from boodebr.org. boodebr.ion provides JSON and XML serialization with a common API (internal and external). boodebr.config provides flexible configuration file handling (similar to INI files, but using JSON/XML with full object pickling).
PyMultimethods is a library that enables users to create multimethods (a.k.a. generic functions) in Python. In other words, you can create multiple versions of the same function/method. The one that is invoked depends on the runtime parameters. This is similar to polymorphism in the sense that the object type determines which version of the function is invoked. Multimethods go beyond the polymorphism found in conventional object oriented languages, however, because all parameters are taken into account (as opposed to only the "implied this", as in C++ or Java). PyMultimethods can also be used to "overload" a function or method.
WikklyText is a Python-based wiki and modular library for creating custom wikitext rendering applications. Its wikitext engine is compatible with the TiddlyWiki markup language. It functions equally well as a wiki-on-a-stick or as a multiuser wiki behind Apache. It includes a Drupal plugin as well.
Pydiction consists of a plugin and a Python script that allows programmers to tab-complete their Python code in Vim by generating a dictionary file of Python modules, and their attributes and methods, for use with Vim's completion feature. It comes with a default dictionary containing the entire Python standard library, keywords, and many 3rd-party modules like PyQT4, Pygame, Twisted, OpenGL, wxPython, PyGTK, MySQLdb, and more.
The eGenix mxODBC Zope Database Adapter (Zope DA) allows you to easily connect your Zope installation to just about any database backend. Unlike Zope's ZODBC Zope DA, the mxODBC Zope DA works on Windows, Linux, and Solaris using the same interface. It implements thread-safe connection pooling and multiple physical connects per logical Zope connection. You can safely run Z SQL Methods in parallel, achieving much better performance than ZODBC Zope DA or similar database adapters under heavy load. This makes it ideal for deployment in clusters and hosting environments where stability and high performance are a priority.
