PyDispatcher provides the Python programmer with a multiple-producer-multiple-consumer signal-registration and routing infrastructure for use in multiple contexts. The mechanism of PyDispatcher ... [More] started life as a highly rated recipe in the Python Cookbook. The SourceForge project aims to include various enhancements to the recipe developed during use in various applications. [Less]

The django queue service is intended to be a lightweight, open-source queuing mechanism along the lines of the Amazon Simple Queue Service. The concepts are based off that API, and the implementation ... [More] is using the Django web framework (python). The queue is intended to be used through a REST interface. In effect, this project is an open source clone of that work. [Less]

gevent is a coroutine-based Python networking library that uses greenlet to provide a high-level synchronous API on top of libevent event loop. Features include: convenient API around ... [More] greenlets familiar synchronization primitives socket module that cooperates WSGI server on top of libevent-http DNS requests done through libevent-dns monkey patching utility to get pure Python modules to cooperate [Less]

EventCal creates HTML calendars for use with Python web applications. What's special about these calendars is that they can include events such as "Meeting with Alice" or "Finish writing letter to ... [More] Bob". Different languages may be used with the calendar. [Less]

A program to scan a variety of websites, locating event announcements in a wide variety of formats, and aggregating the data into a single store.

SpiffSignal is a Python module that implements a simple signal/event mechanism: from SpiffSignal import Trackable class WatchMe(Trackable): def do_something(self): ... [More] self.signal_emit('did-something', 'hello world') def my_callback(arg): print arg foo = WatchMe() foo.signal_connect('did-something', my_callback) foo.do_something() [Less]

YPy is a Yield-based Python application server that uses Stackless Python/the greenlets module for transparent stack switching in Python. YPy is not a web framework, but a web server like Apache with ... [More] mod_python/mod_wsgi for Python or Mongrel for Ruby on Rails. YPy is primarily intended as a WSGI server, though it can be used for other (non-web) applications. See the YPy README.txt for instructions on installing YPy. See BasicWSGIServer for instructions on how to get a basic WSGI application running under YPy. [Less]

There are many problems whose most obvious and elegant solution is a long-running daemon, however, the overhead of defining the daemon's internal workings (forking, logging, pidfile management, signal ... [More] handling, task scheduling, configuration, etc.) is off-putting. Additionally, the sheer amount of complexity involved with implementing concurrency makes a daemon a generally unattractive solution. cdaemon works around these problems, providing classes and mix-ins which take care of much of the boilerplate code associated with typical non-concurrent daemons, while adding concurrency in the form of an event-driven system (the classic Producer/Consumer model).

A python library to implement serial or distributed discrete event simulations. Distributed algorithm to be based on Jayadev Misra.

pyplant is the tentative name for a project researching plant growth via a discrete event simulator, implemented in Python. At the start of this project, we are using SimPy to model the growth of a ... [More] single plant. Once this is complete, we will model a garden plot. The eventual goal is to build a graphical garden game/simulation. This project was started by two undergraduate students: Matthew Harrison (Computer Science, University of Massachusetts Amherst. mobilemharrison {at} gmail) Landon Fowles (Computer Engineering, Kansas State University. landon {at} lfowles.org) [Less]
