我们可以通过调用stop()方法来改变标志位,进而停止线程的执行。 if__name__=="__main__":my_thread=MyThread()my_thread.start()# 启动线程time.sleep(5)# 主线程等待5秒print("Stopping thread...")my_thread.stop()# 改变标志位以终止线程my_thread.join()# 等待线程终止print("Thread has been stop...
print "I am stopping ..." mythread = MyThread() mythread.start() 二、Python中提供的线程超时检测机制 线程的超时与否可以用Python自己提供的机制来检测, 这就是线程的 join() 函数,在python的文档里面可以找到该函数的详细说明(http://docs.python.org/library/threading.html#threading.Thread.join)。 简...

I run an editor, cd wherever, run whatever, and the three are not particularly bound. I can imagine there are disadvantages to that kind of recklessness, as well, and that's not really the style of an IDE which is managing a number of problems. I probably belong in another thread, ...

我也有过类似的问题。它似乎来自于使用python3而不是python2.7。
使用threading模块的Thread类初始化对象然后调用start方法启动线程。 import threading import time def worker(num): time.sleep(1) print('worker-{}'.format(num)) # 创建线程对象 target参数是一个函数, 这个函数即线程要执行的逻辑 threads = [threading.Thread(target=worker, args=(i, ))for i in range...
Thread(target=routine, args=(factory,)).start() reactor.run() bStop = True 一开始我们建立TCP连接, 传入主机地址, 端口, 协议工厂对象作为参数,随后reactor.run挂起运行。下面我们看看ClientFactory基类,因为我们自定义的协议工厂EchoClientFactory派生自它。源码: 代码语言:javascript 复制 class ClientFactory(...
