code:
#-*- coding:utf-8 -*-
from concurrent import futures
import os
import sys
import signal
def test(num):
import time
print os.getpid()
time.sleep(100)
return time.ctime(), num
def handle_interrupt(signum, frame):
print 'CAUGHT SIGINT!!!!!!!!!!!!!!!!!!!'
sys.exit(1)
def main():
signal.signal(signal.SIGTERM, handle_interrupt) # kill
signal.signal(signal.SIGINT, handle_interrupt) # Ctrl+C
signal.signal(signal.SIGQUIT, handle_interrupt) # Ctrl+\
with futures.ProcessPoolExecutor(max_workers=3) as executor:
print 'id:', id(executor)
future1 = executor.submit(test,1)
future2 = executor.submit(test,2)
print future1
print future1
print future1.result()
print future2.result()
if __name__ == '__main__':
main()
