Pymbian http://pymbian.sourceforge.net/ is designed to be a pedagogical device, helping to understand underlying principles of Symbian OS. It enables programmer to use regular Python to implement prototypes using Symbian C++ programming paradigms.

Specially, it models following features of Symbian OS:

* Threads, Timers, Semaphores
* Low-level asynchronous services (thread request semaphores, request status signaling & waiting, etc)
* High-level asynchronous service (active schedulers and active objects)
* client/server framework

source example : This source file shows how Active Scheduler, Active Object and platform timer service is used:

import sys
import thread
import time

from pymbian.base import CActiveScheduler, CActive
from pymbian.std import KErrNone, User, RThread, KRequestPending, RTimer
from pymbian.std import KErrCancel

def do_example():
    print "starting example"

    scheduler = CActiveScheduler()
    CActiveScheduler.Install(scheduler)

    ao = TestAO()
    ao.IssueRequest()

    scheduler.Start()

    print "closing down example"

class TestAO(CActive):
    def __init__(self):
        CActive.__init__(self)
        CActiveScheduler.Add(self)        
        self.service = RTimer()

    def IssueRequest(self):
        print "issuing request for 1 sec delay"
        self.service.After(self.iStatus, 1)
        self.SetActive()

    def Run(self):
        print "TestAO.Run called"
        print "closing down activescheduler"
        CActiveScheduler.Stop()

    def DoCancel(self):
        self.service.Cancel()


def main():
    do_example()

if __name__ == "__main__":
    main()
