线程池

 

from concurrent.futures import ProcessPoolExecutor
from time import sleep

def task(message):
   sleep(2)
   return message

def main():
   executor = ProcessPoolExecutor(5)
   future = executor.submit(task, ("Completed"))
   print(future.done())
   sleep(2)
   print(future.done())
   print(future.result())

if __name__ == '__main__':
    main()

输出：

False
False
Completed
