    import pexpect
    import datetime
    from threading import Thread
    host=["192.168.1.1","192.168.1.123","192.168.2.1",
    "192.168.1.1","192.168.1.123","192.168.2.1",
    "192.168.1.1","192.168.1.123","192.168.2.1",
    "192.168.1.1","192.168.1.123","192.168.2.1",
    "192.168.1.1"]
    report_ok=[]
    report_error=[]
    class PING(Thread):
      def __init__(self,ip):
        Thread.__init__(self)
        self.ip=ip
      def run(self):
        Curtime = datetime.datetime.now()  
        #Scrtime = Curtime + datetime.timedelta(0,minute,0) 
        #print("[%s]主机[%s]" % (Curtime,self.ip))
        ping=pexpect.spawn("ping -c1 %s" % (self.ip))
        check=ping.expect([pexpect.TIMEOUT,"1 packets transmitted, 1 received, 0% packet loss"],2)
        if check == 0:
          print("[%s] 超时 %s" % (Curtime,self.ip))
        elif check == 1:
          print ("[%s] %s 可达" % (Curtime,self.ip))
        else:
          print("[%s] 主机%s 不可达" % (Curtime,self.ip))
    #多线程同时执行
    T_thread=[]
    for i in host:
      t=PING(i)
      T_thread.append(t)
    for i in range(len(T_thread)):
      T_thread[i].start()
    #
    #print ("\n=========问题主机情况如下==========\n")
    #output(report_error)
    #print ("\n=========正常主机情况如下==========\n")
    #output(report_ok)

执行结果：
