我自己的方法结合了上面的几个答案:

def ping(host, show_log=False, package_count=1):
    ping.param = "-n" if platform.system().lower() == 'windows' else "-c"
    result = subprocess.run(['ping', ping.param, str(package_count), host],
                            stdout=subprocess.PIPE,
                            stderr=subprocess.STDOUT)
    output = result.stdout
    if show_log:
        print('return code: ', result.returncode)
        print(output.decode("utf-8"))
    return result.returncode == 0 and (b'TTL=' in output or b'ttl=' in output)

在OSX Monterey上测试。

我的版本的ping函数:

适用于Python 3.5及更高版本，适用于Windows和Linux。 在Windows上，如果ping命令失败且“目标主机不可达”，则返回False。 并且不显示任何输出，无论是弹出窗口还是命令行。

import platform, subprocess

def ping(host_or_ip, packets=1, timeout=1000):
    ''' Calls system "ping" command, returns True if ping succeeds.
    Required parameter: host_or_ip (str, address of host to ping)
    Optional parameters: packets (int, number of retries), timeout (int, ms to wait for response)
    Does not show any output, either as popup window or in command line.
    Python 3.5+, Windows and Linux compatible
    '''
    # The ping command is the same for Windows and Linux, except for the "number of packets" flag.
    if platform.system().lower() == 'windows':
        command = ['ping', '-n', str(packets), '-w', str(timeout), host_or_ip]
        # run parameters: capture output, discard error messages, do not show window
        result = subprocess.run(command, stdin=subprocess.DEVNULL, stdout=subprocess.PIPE, stderr=subprocess.DEVNULL, creationflags=0x08000000)
        # 0x0800000 is a windows-only Popen flag to specify that a new process will not create a window.
        # On Python 3.7+, you can use a subprocess constant:
        #   result = subprocess.run(command, capture_output=True, creationflags=subprocess.CREATE_NO_WINDOW)
        # On windows 7+, ping returns 0 (ok) when host is not reachable; to be sure host is responding,
        # we search the text "TTL=" on the command output. If it's there, the ping really had a response.
        return result.returncode == 0 and b'TTL=' in result.stdout
    else:
        command = ['ping', '-c', str(packets), '-w', str(timeout), host_or_ip]
        # run parameters: discard output and error messages
        result = subprocess.run(command, stdin=subprocess.DEVNULL, stdout=subprocess.DEVNULL, stderr=subprocess.DEVNULL)
        return result.returncode == 0

你想怎么用就怎么用。

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"))

在四处寻找之后，我最终编写了自己的ping模块，该模块旨在监视大量地址，是异步的，并且不使用大量系统资源。你可以在这里找到它:https://github.com/romana/multi-ping/它是Apache授权的，所以你可以在你的项目中以任何你认为合适的方式使用它。

实施我自己的方法的主要原因是其他方法的限制:

这里提到的许多解决方案都需要将exec输出到命令行实用程序。如果您需要监控大量的IP地址，这是非常低效和资源消耗的。 其他人提到了一些较老的python ping模块。我看了这些，最后，他们都有这样或那样的问题(比如没有正确设置数据包id)，不能处理大量地址的ping-ing。

使用这个，它在python 2.7上测试过，工作很好，如果成功，它返回以毫秒为单位的ping时间，失败时返回False。

import platform,subproccess,re
def Ping(hostname,timeout):
    if platform.system() == "Windows":
        command="ping "+hostname+" -n 1 -w "+str(timeout*1000)
    else:
        command="ping -i "+str(timeout)+" -c 1 " + hostname
    proccess = subprocess.Popen(command, stdout=subprocess.PIPE)
    matches=re.match('.*time=([0-9]+)ms.*', proccess.stdout.read(),re.DOTALL)
    if matches:
        return matches.group(1)
    else: 
        return False

在linux上，可以创建ICMP数据报(不是原始)套接字，而不需要root(或setuid或CAP_NET_RAW): https://unix.stackexchange.com/a/592914。最后我得到了

    sock.settimeout(10.0)

    payload = struct.pack('L', start_time)
    sock.sendto(encode(payload), (destination, 0))
    while (time.time_ns() - start_time) // 1_000_000_000 < 10:
        try:

        except socket.timeout:

        message_type, message_code, check, identifier, sequence_number = struct.unpack('bbHHh', data[:8])
        if source == (destination, 0) and message_type == ICMP.ECHO_REPLY and data[8:] == payload:

    # calculate checksum with check set to 0
    checksum = calc_checksum(icmp_header(ICMP.ECHO_REQUEST, 0, 0, 1, 1) + payload)
    # craft the packet again with the checksum set
    return icmp_header(ICMP.ECHO_REQUEST, 0, checksum, 1, 1) + payload

def icmp_header(message_type, message_code, check, identifier, sequence_number) -> bytes:
