今天用Python写了一段小代码,实现的功能是ping某一个网段的所有ip,然后将ping的结果提取出来,输出可以ping通的ip以及往返时间。
初学Python,写得简陋,各位大侠多多指教。
正则表达式请根据自己的系统进行调整,我这个是中文win7下的结果
Python3.3下测试没问题
ping测试的过程中内存占用较大,不知道可以怎么改进
__author__ = ‘wucl‘ import subprocess, re, _thread, queue, time, threading print(‘Ping Processing, Please Wait...‘) regex=re.compile(‘最短 = (\d+)ms,最长 = (\d+)ms,平均 = (\d+)ms‘) ipPrefix=‘192.168.1.‘ decoding=‘gbk‘ def ping(ip): p=subprocess.Popen([‘ping.exe‘,ip],stdout=subprocess.PIPE) out=p.stdout.read() result=regex.findall(out.decode(decoding)) if result: printQueue.put(‘%15s 最短=%2dms,最长=%2dms,平均=%2dms‘ %(ip,int(result[0][0]),int(result[0][1]),int(result[0][2]))) return (ip,result[0]) def resultPrint(printQueue): while True: try: data=printQueue.get() except queue.Empty: pass else: with safeprint: print(data) printQueue=queue.Queue() safeprint=_thread.allocate_lock() thread=threading.Thread(target=resultPrint,args=(printQueue,)) thread.daemon=True thread.start() waitfor=[] for i in range(1,255): ip=ipPrefix+str(i) thread=threading.Thread(target=ping,args=(ip,)) waitfor.append(thread) thread.start() for thread in waitfor: thread.join() print(‘Ping End.‘) input(‘Press Enter to quit.‘)
