python 多線程 ping

多線程操作可按如下例子實現

#!/usr/bin/env python#encoding: utf8import subprocessfrom threading import Thread   from Queue import Queue  def ping(i,queue):      while True:          ip=queue.get()          #print 'Thread %s pinging %s' %(i,ip)          ret=subprocess.call('ping -c 1 %s' % ip,shell=True,stdout=subprocess.PIPE)          if ret==0:              print '%s is alive!' %ip          elif ret==1:              print '%s is down...'%ip          queue.task_done()    q=Queue()ips=['127.0.0.1','116.56.148.187','47.97.184.87']#command = "awk '{print $1}' iplist"#p = subprocess.Popen(command,shell=True,stdout=subprocess.PIPE)#ips = p.stdout.read().split('\n')#while '' in ips:#    ips.remove('')    for i in range(5):      t=Thread(target=ping,args=(i,q))      t.setDaemon(True)      t.start()  for ip in ips:      q.put(ip)  q.join()
