All PySymbian articles have been archived. PySymbian is no longer maintained by Nokia and is not guaranteed to work on more recent Symbian devices. It is not possible to submit apps to Nokia Store.

This code snippet lists open threads on Symbian using PySymbian. The threads can be used to manipulate asyncronous processes.

Defining Thread

In this code the thread class is create. The class sum numbers and store in result list after run

class process(threading.Thread):
    value = 0
    tx = 0
    def sum(self):
        x = 1
        for i in range(1, self.value):
            x = x + i
        return x
 
    def run(self):
        e32.ao_yield() # Define above normal process 
        x = self.sum()
        processResult.append({ 'thread' : self.tx, 'result': x })
        print "%s %s" % (self.tx,x)

Main process

The main process create threads class with random number and start process with it thread.

processList = [] 
processResult = [] 
 
class Principal(threading.Thread):  
  def pop(self):
    for i in range(200):
      p = process()
      p.value = random.randint(1, 10000)
      p.tx = i
      processList.append(p)
 
    for i in processList:
      i.start()   
 
  def run(self):
    e32.ao_yield()
    self.pop()
 
principal = Principal()
principal.start()
