"Storm is an object-relational mapper (ORM) for Python developed at Canonical. The project has been in development for more than a year for use in Canonical projects such as [WWW] Launchpad, and has recently been released as an open-source product."
"Werkzeug started as simple collection of various utilities for WSGI applications and has become one of the most advanced WSGI utility modules. It includes a powerful debugger, full featured request and response objects, HTTP utilities to handle entity tags, cache control headers, HTTP dates, cookie handling, file uploads, a powerful URL routing system and a bunch of community contributed addon modules."
"python4ply is a Python parser for the Python language. The grammar definition uses PLY, a parser system for Python modelled on yacc/lex. The parser rules use the "compiler" module from the standard library to build a Python AST and to generate byte code for .pyc file.
You might use python4ply to experiment with variations in the Python language. The PLY-based lexer and parser are much easier to change than the C implementation Python itself uses or even the ones written in Python which are part of the standard library. This tutorial walks through examples of how to make changes in different levels of the system."
"Yould is a generator for pronounceable random words. The text below was generated by Yould. Play with the parameters and regenerate as much as you want."
"Use SAGE for studying a huge range of mathematics, including algebra, calculus, elementary to very advanced number theory, cryptography, numerical computation, commutative algebra, group theory, combinatorics, graph theory, and exact linear algebra."
"pybonjour provides a pure-Python interface to [WWW] Apple Bonjour and compatible [WWW] DNS-SD libraries (such as [WWW] Avahi). It allows [WWW] Python scripts to take advantage of [WWW] Zero Configuration Networking (Zeroconf) to register, discover, and resolve services on both local and wide-area networks. Since pybonjour is implemented in pure Python, scripts that use it can easily be ported to Mac OS X, Windows, Linux, and other systems that run Bonjour. pybonjour is [WWW] free software, distributed under the [WWW] MIT license."
"Duplicity backs directories by producing encrypted tar-format volumes and uploading them to a remote or local file server. Because duplicity uses librsync, the incremental archives are space efficient and only record the parts of files that have changed since the last backup. Because duplicity uses GnuPG to encrypt and/or sign these archives, they will be safe from spying and/or modification by the server."
