# Documentation for SimPy

SimPy is a process-based discrete-event simulation language based on standard Python. It provides the modeller with components of a simulation model including processes, for active components like customers, messages, and vehicles, and resources, for passive components that form limited capacity congestion points like servers, checkout counters, and tunnels. It also provides monitor variables to aid in gathering statistics. Random variates are provided by the standard Python random module.

It is based on ideas from Simula and Simscript and provides efficient implementation of co-routines using Python’s generators capability. It requires Python 2.6 or later including Python 3.x. It was first released in 2002 under the GNU LGPL.
