mtail is a small tail workalike that performs output coloring using ANSI escape sequences (although the sequences are overridable, so you could cause it to output something else, e.g., HTML font tags). It is written in python, is fairly small, and should be relatively platform-independent.
QWPython is a Python-powered QuakeWorld dedicated server. The core engine has been wrapped up as a Python module and altered to call back to Python to execute Quake game logic. A QuakeC - Python translator is also included, along with pre-translated versions of Deathmatch and Capture-The-Flag.
psycopg is a PostgreSQL database adapter for the Python programming language. Its main advantages are that it supports the full Python DBAPI 2.0 and it is thread safe at level 2. It was designed for heavily multi-threaded applications that create and destroy lots of cursors and make a conspicuous number of concurrent INSERTs or UPDATEs. The psycopg distribution includes ZPsycopgDA, a Zope Database Adapter.
E-Cell System is an object-oriented software suite for modelling, simulation, and analysis of large scale complex systems such as biological cells. It allows many components, driven by multiple algorithms with different timescales, to coexist. The core library is written in C++ with a Python binding, and frontend software uses Python.
PyTraffic is a Python version of the board game Rush Hour created by Binary Arts Coporation. The goal is to remove the red car out of the grid through the slot on the right. To do this you have to slide the other cars out of the way. PyTraffic comes with about 19,000 puzzles ranging from intermediate to expert, and has an extremely smart hint facility which is able to find the best move in every position.
Synopsis is a multi-language source code introspection tool that provides a variety of representations for the parsed code to enable further processing such as documentation extraction, reverse engineering, and source-to-source translation. It provides a framework of C++ and Python APIs to access these representations and allows Processor objects to be defined and composed into processing pipelines, making this framework very flexible and extensible.
MapIt! is a simple Web-mapping application implemented in Python that lets you navigate raster maps through your Web browser. It lets you zoom in and out, and select objects and object classes that are highlighted on the map. MapIt! can be integrated with an existing Web server in several ways: as a CGI script, Fast-CGI, or in Apache with mod_python. It can also serve GIS results over the Web.
