i2py provides tools for converting programs and scripts written in Research System Inc.'s IDL programming language to Python. It is not an IDL-compatible front end for the Python interpreter, nor does it make any attempt to replicate the functionality of the IDL standard library. Rather, its only purpose is to perform source-to-source conversion of legacy IDL code to Python. Currently, it supports only procedural IDL, although support for object-oriented code may be added in the future.
Pygme is an GTK+ frontend for mplayer that was written with audio and video songs in mind rather than movies. It has a searchable media library, which can be used to enqueue songs in a playlist. It also has support for ID3 tag information. The media library and playlist are stored as databases using SQLite.
PGAPy is a wrapper for pgapack, the parallel genetic algorithm library, a powerful genetic algorithm library. PGAPy wraps this library for use with Python. Pgapack is one of the most complete and accurate genetic algorithm implementations out there with a lot of features for experimentation.
python-amarok is a fairly complete amaroK remote control class for Python. It is extremely useful for amaroK scripts and other applications and makes it possible to remote control amaroK by calling methods from an amaroKProxy instance. In addition, it implements the Observer/Observable pattern so you can deal with events in an object oriented, loosely coupled fashion. Even better, you can call an amaroKProxy instance's collection.getSong(filename) method to get a Song object, with track, artist, album name, and elegant "Artist - Track name" strings.
Twisted Web includes an HTTP/1.0 protocol implementation for both servers and clients. It also includes a resource framework for implementing rich, dynamic web applications. It includes support for authentication either via HTTP AUTH, session URLs, or session cookies. It supports CGIs and a custom PB-based distribution mechanism for serving content from separate, persistent processes. It includes SOAP and XML-RPC support for both clients and servers. It also makes it particularly easy to deploy new servers with novel or ephemeral use-cases, often with only a single short command.
