 import subprocess
 import time
 ip="10.210.202."

 def aa():
     ks=int(time.time()) #记录开始时间
     num1=num2=0
     for i in range(1,254):
         ips=ip+str(i)   
         ret=subprocess.call("ping -n 1 -w 1 %s " % ips)
         if ret == 0:
            print (ips,"+++++++++++++Online ")
            num1=num1+1
         else:
            # print (ips,"-------------Offline")
             num2=num2+1

     js=int(time.time())  #记录结束时间
     print("time（秒）:",js-ks,"s")  #打印并计算用的时间，s秒
     print("ON_line:",num1,"    OFF_line:",num2)

 while True:
     aa()
     hd=input("是否继续【Y/N】：")
     try:
         if hd=="Y" or hd=="y":
             pass
     except :pass
     if hd=="N" or hd=="n":
         print("Goodbye!......")
         time.sleep(3)
         break
 效果图如下：
