sending data to thread

[Ofnuts]

The easiest way is to define a function that will be the core of your thread, then create threads that will call this function and pass it different arguments (names in example below, graph number for you):

import threading,time,random

RUNS=4
THREADNAMES=['ONE','TWO','THREE']

def threadFunction(id):
    print "Starting thread %s" % id
    for _ in range(RUNS):
        time.sleep(random.uniform(.5,2.5))
        print 'Thread %s still alive' % id
    print "Ending thread %s" % id


# create the threads
threads=[threading.Thread(target=threadFunction,args=(id,)) for id in THREADNAMES]
         
# make them run         
for t in threads:
    t.start()
    
# make sure they are all ended before existing:
for t in threads:
    t.join()

However, due to the Global Interpreter Lock there is no real concurrent execution of threads in Python, so you won't run on more core with Python threading.
