Python multi-threaded batch ping host IP script

Python writes a multithreaded Ping host IP script 1. Write a script to Ping the host IP first

ping_ip.py

import subprocessimport time# 记录开始执行的时间start_time = time.time()# 定义用来 ping 的254 个 ipip_list = [‘10.3.1.‘+str(i) for i in range(1,255)]  for ip in ip_list:    res = subprocess.call(‘ping -n 2 -w 5 %s‘ % ip,stdout=subprocess.PIPE)  # linux 系统将 ‘-n‘ 替换成 ‘-c‘    print(ip,True if res == 0 else False)print(‘执行所用时间：%s‘ % (time.time() - start_time))

2. Change the script to multiple threads

ping_threading.py

import threadingimport subprocessimport timefrom queue import Queue# 定义工作线程WORD_THREAD = 50# 将需要 ping 的 ip 加入队列IP_QUEUE = Queue() for i in range(1,255):    IP_QUEUE.put(‘10.3.1.‘+str(i))# 定义一个执行 ping 的函数def ping_ip():    while not IP_QUEUE.empty():        ip = IP_QUEUE.get()        res = subprocess.call(‘ping -n 2 -w 5 %s‘ % ip,stdout=subprocess.PIPE)  # linux 系统将 ‘-n‘ 替换成 ‘-c‘        # 打印运行结果        print(ip,True if res == 0 else False)if __name__ == ‘__main__‘:    threads = []    start_time = time.time()    for i in range(WORD_THREAD):        thread = threading.Thread(target=ping_ip)        thread.start()        threads.append(thread)    for thread in threads:        thread.join()    print(‘程序运行耗时：%s‘ % (time.time() - start_time))
