有一个名为pyping的模块可以做到这一点。可以用pip安装

pip install pyping

它使用起来非常简单，但是，当使用这个模块时，您需要root访问权限，因为它在底层制作原始数据包。

import pyping

r = pyping.ping('google.com')

if r.ret_code == 0:
    print("Success")
else:
    print("Failed with {}".format(r.ret_code))

我使用这篇文章中回答的想法，但只使用更新的推荐子进程模块和python3:

import subprocess
import platform

operating_sys = platform.system()
nas = '192.168.0.10'

def ping(ip):
    # ping_command = ['ping', ip, '-n', '1'] instead of ping_command = ['ping', ip, '-n 1'] for Windows
    ping_command = ['ping', ip, '-n', '1'] if operating_sys == 'Windows' else ['ping', ip, '-c 1']
    shell_needed = True if operating_sys == 'Windows' else False

    ping_output = subprocess.run(ping_command,shell=shell_needed,stdout=subprocess.PIPE)
    success = ping_output.returncode
    return True if success == 0 else False

out = ping(nas)
print(out)

使用python3中的套接字包:

import socket

def ping_server(server: str, port: int, timeout=3):
    """ping server"""
    try:
        socket.setdefaulttimeout(timeout)
        s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
        s.connect((server, port))
    except OSError as error:
        return False
    else:
        s.close()
        return True

因为我喜欢让我的Python程序在2.7和3版本上通用。在Linux, Mac OS和Windows平台上，我必须修改现有的示例。

# shebang does not work over all platforms
# ping.py  2016-02-25 Rudolf
# subprocess.call() is preferred to os.system()
# works under Python 2.7 and 3.4
# works under Linux, Mac OS, Windows

def ping(host):
    """
    Returns True if host responds to a ping request
    """
    import subprocess, platform

    # Ping parameters as function of OS
    ping_str = "-n 1" if  platform.system().lower()=="windows" else "-c 1"
    args = "ping " + " " + ping_str + " " + host
    need_sh = False if  platform.system().lower()=="windows" else True

    # Ping
    return subprocess.call(args, shell=need_sh) == 0

# test call
print(ping("192.168.17.142"))

下面是一个使用Python的子进程模块和底层操作系统提供的ping CLI工具的解决方案。在Windows和Linux上测试。支持设置网络超时。不需要根权限(至少在Windows和Linux上)。

import platform
import subprocess

def ping(host, network_timeout=3):
    """Send a ping packet to the specified host, using the system "ping" command."""
    args = [
        'ping'
    ]

    platform_os = platform.system().lower()

    if platform_os == 'windows':
        args.extend(['-n', '1'])
        args.extend(['-w', str(network_timeout * 1000)])
    elif platform_os in ('linux', 'darwin'):
        args.extend(['-c', '1'])
        args.extend(['-W', str(network_timeout)])
    else:
        raise NotImplemented('Unsupported OS: {}'.format(platform_os))

    args.append(host)

    try:
        if platform_os == 'windows':
            output = subprocess.run(args, check=True, universal_newlines=True).stdout

            if output and 'TTL' not in output:
                return False
        else:
            subprocess.run(args, check=True)

        return True
    except (subprocess.CalledProcessError, subprocess.TimeoutExpired):
        return False

这个脚本适用于Windows，也适用于其他操作系统: 它可以在Windows, Debian和macosx上工作，需要在solaris上测试。

import os
import platform


def isUp(hostname):

    giveFeedback = False

    if platform.system() == "Windows":
        response = os.system("ping "+hostname+" -n 1")
    else:
        response = os.system("ping -c 1 " + hostname)

    isUpBool = False
    if response == 0:
        if giveFeedback:
            print hostname, 'is up!'
        isUpBool = True
    else:
        if giveFeedback:
            print hostname, 'is down!'

    return isUpBool

print(isUp("example.com")) #Example domain
print(isUp("localhost")) #Your computer
print(isUp("invalid.example.com")) #Unresolvable hostname: https://tools.ietf.org/html/rfc6761
print(isUp("192.168.1.1")) #Pings local router
print(isUp("192.168.1.135")) #Pings a local computer - will differ for your network
