Python并发编程：线程、进程与调度
线程的使用
在Python中，线程是实现并发的一种方式。通过使用queue模块，可以让线程的使用更加简单和安全。以下是一个简单的线程示例代码：
worker.start() #spawn pool of arping threads for i in range(num_arp_threads): worker = Thread(target=arping, args=(i, out_queue)) worker.setDaemon(True) worker.start() print "Main Thread Waiting" #ensures that program does not exit until both queues have been emptied in_queue.join() out_queue.join() print "Done"运行上述代码后，输出可能如下：
python2.5 ping_thread_basic_2.py Main Thread Waiting Thread 0: Pinging 10.0.1.1 Thread 1: Pinging 10.0.1.3 Thread 2: Pinging 10.0.1.11 Thread 0: Pinging 10.0.1.51 IP Address: 10.0.1.1 | Mac Address: [00:00:00:00:00:01] IP Address: 10.0.1.51 | M
