Hi. I am fairly new to Python programming and am having some trouble
wrapping my head around threading.
This is a very basic example of what I am trying to do, and would
greatly appreciate having this code hacked to pieces so that I can
learn from you folks with experience.
What I would like to learn from this example is how to use threads to
call on other classes and append/modify results in a list outside of
scope (basically keep track of variables throught the total threading
process and return them somehow afterwards ). I was thinking about
using some sort of global, but I am not sure what the best approach to
this is.
Thanks kindly for any assistance you may be able to offer.

import time, random, threading
order = []
class Foo:
def __init__(self, person):
print "\nFoo() recieved %s\n" % person
class Bar(threading.Thread, Foo):
def __init__(self, name):
threading.Thread.__init__(self, name = name)
self.curName = name
def run(self):
global order
sleepTime = random.randrange(1,6)
print "Starting thread for %s in %d seconds" % \
(self.getName(), sleepTime)
time.sleep(sleepTime)
Foo.__init__(self,self.getName())
print "%s's thread has completed" % self.getName()
order.append(self.getName())
def main():
for person in ['Bill','Jane','Steve','Sally','Kim']:
thread = Bar(person)
thread.start()
# How do I print "order" after all the threads are complete?
print "\nThreads were processed in the following order:"
for i, person in enumerate(order): print "%d. %s" % (i+1,person)
if __name__ == "__main__":
main()
