Is Stackless Python THE Way?

October 23rd, 2007

Code with Stackless Python

#
# pingpong_stackless.py
#

import stackless

ping_channel = stackless.channel()
pong_channel = stackless.channel()

def ping():
    while ping_channel.receive(): #blocks here
        print "PING" 
        pong_channel.send("from ping")

def pong():
    while pong_channel.receive():
        print "PONG" 
        ping_channel.send("from pong")

stackless.tasklet(ping)()
stackless.tasklet(pong)()

# we need to 'prime' the game by sending a start message
# if not, both tasklets will block
stackless.tasklet(ping_channel.send)('startup')

stackless.run()

And it runs…forever.
