tinypy is a minimalist implementation of Python in 64k of code. It includes a parser and bytecode compiler written in python. tinypy runs on its own C-based virtual machine with garbage collection. It supports a fairly decent subset of Python, including classes with single inheritance, functions with variable or keyword arguments, strings, lists, dicts, numbers, modules, list comprehensions, exceptions with full traceback, some builtins, and several modules.
pg_pqueue is a Python package that provides low-level PQ protocol classes for interacting with a PostgreSQL database. It supports version 3.0 of the protocol. The package also provides a basic protocol transaction class. This class keeps the state of the protocol in an interrupt safe manner, and validates the integrity of the communication as messages are received. In general, you probably will never use this package directly, unless you are writing a driver.
pg_greentrunk provides fundamental components of GreenTrunk, an interface protocol (API) for using a PostgreSQL database with Python. It provides an interface for implementations to use, and provides documentation in the form of Python modules to allow immediate access to object descriptions, even when inside a Python console.
txOpenID is an implementation of the OpenID Identity Provider specification, written using Twisted Web and Divmod's Nevow. It reads authentication data and user Web sessions out of a MySQL database using MySQLdb and Twisted Enterprise's adbapi layer. txOpenID currently supports version 1.1 of the OpenID specification.
Hasard is a pseudo-random number generator (PRNG) library. It includes multiple engines (algorithms): Park-Miller, Mersenne Twister, Linux device (/dev/urandom or /dev/random), and more. It has a simple but powerful API. For example, a PRNG seed can be generated using strong entropy (using a hardware random number generator like /dev/random on Linux). The library is written in C, and a Python binding is available. The word "hasard" is the French word for "randomness" or "chance".
