Hi all, is there a way in python to get back the value of the function
passed to a thread once the thread is finished? Something like
pthread_join() in C?
Thanks, Mattia
use a Queue to pass the value out?
Yes, it can be a solution, but are you indirectly telling me that there
is no way then?
looking at the threading.py source code, it is clear that the return
value of Thread.run() is ignored, but this is a workaround:
import threading
class MyThread(threading.Thread):
def join(self):
super(MyThread, self).join()
return self.result
class Worker(MyThread):
def run(self):
total = 0
for i in range(random.randrange(10000, 100000)):
total += i
self.result = total
import random
ts = [Worker() for i in range(100)]
for t in ts:
t.start()
for t in ts:
print t.join()
