import time

from datetime import datetime

from multiprocessing.dummy import Pool as ThreadPool

from functools import partial

def add(x, y):

print(datetime.now(), "enter add func...")

time.sleep(2)

print(datetime.now(), "leave add func...")

return x+y

def add_wrap(args):

add(*args)

return

if __name__ == "__main__":

pool = ThreadPool(4) # 池的大小为4

print(pool.map(add_wrap, [(1,2),(3,4),(5,6)]))

#close the pool and wait for the worker to exit

pool.close()

pool.join()
