如何使用python检查ping？

import subprocess

def ping(host):
    # 对于Windows系统，使用 '-n' 参数
    # 对于Linux/Unix系统，使用 '-c' 参数
    param = '-n' if platform.system().lower() == 'windows' else '-c'

    # 构建命令
    command = ['ping', param, '1', host]

    return subprocess.call(command) == 0

# 使用示例
host = 'www.example.com'
if ping(host):
    print(f"{host} is reachable.")
else:
    print(f"{host} is not reachable.")

pip install ping3

from ping3 import ping, exceptions

def check_ping(host):
    try:
        response_time = ping(host)
        if response_time is not None:
            print(f"{host} is reachable. Response time: {response_time} ms")
        else:
            print(f"{host} is not reachable.")
    except exceptions.PingError as e:
        print(f"An error occurred while pinging {host}: {e}")

# 使用示例
check_ping('www.example.com')
