如何在python中停止多进程

Question

当尝试在 for 循环上运行多处理时，所有进程都在执行，但程序没有终止并继续运行。

处理完列表中的所有元素后，如何停止程序？

def multiprocess_for_loop(*args, list_to_iter_over, function):
# the element in iterable is the first argument in the function
output = Queue()
processes = [Process(target=function, args=(elem,) + args) for elem in list_to_iter_over]
logging.info(f"start multiprocess for-loop on list: {list_to_iter_over}")
for p in processes:
    p.start()

results = []
for p in processes:
    results.append(output.get())

for p in processes:
    p.join()

logging.info("finished multiprocessing for-loop")
return results

Answer 1

每个进程都写在队列上？ 如果一个进程没有写进去，你的代码就会一直卡在那里。
