python ping3多线程ping测试

可以使用Python的ping3库和threading库来实现多线程ping测试。下面是一个简单的示例代码：

import ping3
import threading

HOSTS = [
    "www.google.com",
    "www.baidu.com",
    "www.github.com",
    "www.stackoverflow.com"
]

class PingThread(threading.Thread):
    def __init__(self, host):
        threading.Thread.__init__(self)
        self.host = host

    def run(self):
        response_time = ping3.ping(self.host)
        if response_time is not None:
            print(f"{self.host} is alive. Response time: {response_time} ms")
        else:
            print(f"{self.host} is down.")

if __name__ == "__main__":
    threads = []
    for host in HOSTS:
        thread = PingThread(host)
        threads.append(thread)
        thread.start()

    for thread in threads:
        thread.join()

这个示例代码会创建多个PingThread线程来分别ping指定的主机，当收到响应时，会输出相应的信息。可以根据需要修改HOSTS列表中的主机名。
