用 windows 写 Python 真的大丈夫？

经常遇到诡异的问题，换 ubuntu 就没事了。 比如说：

import multiprocessing, time, queue # g_queue = queue.Queue() g_queue = multiprocessing.Queue() c = multiprocessing.cpu_count() def init_queue(): print("init g_queue start") while not g_queue.empty(): g_queue.get() for _index in range(10): g_queue.put(_index) print("init g_queue end") def task_io(task_id): print("IOTask[%s] start" % task_id) while not g_queue.empty(): try: data = g_queue.get(block=True, timeout=1) print("IOTask[%s] get data: %s" % (task_id, data)) time.sleep(1) except Exception as excep: print("IOTask[%s] error: %s" % (task_id, str(excep))) print("IOTask[%s] end" % task_id) if __name__ == '__main__': print("cpu count:", multiprocessing.cpu_count(), "\n") print("========== 多进程执行 IO 密集型任务 ==========") init_queue() time_0 = time.time() process_list = [multiprocessing.Process(target=task_io, args=(i,)) for i in range(c)] for p in process_list: p.start() for p in process_list: if p.is_alive(): p.join() print("结束：", time.time() - time_0, "\n") 

完全拿不到 queue 里面的东西，直接当空气了。
