collection of modules to build distributed and reliable concurrent systems
collection of modules to build distributed and reliable concurrent systems in Python.
A simple example showing how to create a consumer and use other actor function to feed it.
import flower messages =  sources =  def consumer(): # wait for coming message in the current actor while True: source, msg = flower.receive() if not msg: break print("got message from %s: %s" % (source.ref, msg)) def publisher1(ref): # an actor sending messages to the consumer msg = ['hello', 'world'] for s in msg: flower.send(ref, s) def publisher2(ref): msg = ['brave', 'new', 'world', ''] for s in msg: flower.send(ref, s) ref_consumer = flower.spawn(consumer) flower.spawn(publisher1, ref_consumer) flower.spawn(publisher2, ref_consumer) flower.run()
$ python examples/actor_example.py got message from 1: hello got message from 2: brave got message from 1: world got message from 2: new got message from 2: world
Flower requires Python superior to 2.6 (yes Python 3 is supported)
