python中使用多进程multiprocessing并获取子进程的返回值

import random
import time
import multiprocessing


def worker(name, q):
    t = 0
    for i in range(10):
        print(name + " " + str(i))
        x = random.randint(1, 3)
        t += x
        time.sleep(x * 0.1)
    q.put(t)


q = multiprocessing.Queue()
jobs = []
for i in range(10):
    p = multiprocessing.Process(target=worker, args=(str(i), q))
    jobs.append(p)
    p.start()

for p in jobs:
    p.join()

results = [q.get() for j in jobs]
print(results)
