本文通过 4个example 介绍python中多线程package —— threading的常用用法, 包括调用多线程, 同步队列类Queue, Ctrl+c结束多线程。 example1. 调用10个线程, 分别打印0~4, 每打印一个数pause一秒钟。 code如下所示, 在test()函数中用threading.Thread建立10个线程; 一种方法是不要将这些线程设置为守护线程,如...

multiprocessing模块用来开启子进程,并在子进程中执行我们定制的任务(比如函数),该模块与多线程模块threading的编程接口类似。 multiprocessing模块的功能众多:支持子进程、通信和共享数据、执行不同形式的同步,提供了Process、Queue、Pipe、Lock等组件。 需要再次强调的一点是:与线程不同,进程没有任何共享状态,进程修改的...

Using the blocking mechanism of wait, you can pause and resume, and then cooperate with the cycle judgment flag to achieve exit. The following is a code example: #!/usr/bin/env python # coding: utf-8 import threading import time ...
