使用Multi-ping (pip install multiPing)，我做了这个简单的代码(简单地复制和粘贴，如果你愿意!):

from multiping import MultiPing

def ping(host,n = 0):
    if(n>0):
        avg = 0
        for i in range (n):
            avg += ping(host)
        avg = avg/n
    # Create a MultiPing object to test hosts / addresses
    mp = MultiPing([host])

    # Send the pings to those addresses
    mp.send()

    # With a 1 second timout, wait for responses (may return sooner if all
    # results are received).
    responses, no_responses = mp.receive(1)


    for addr, rtt in responses.items():
        RTT = rtt


    if no_responses:
        # Sending pings once more, but just to those addresses that have not
        # responded, yet.
        mp.send()
        responses, no_responses = mp.receive(1)
        RTT = -1

    return RTT

用法:

#Getting the latency average (in seconds) of host '192.168.0.123' using 10 samples
ping('192.168.0.123',10)

如果你想要一个单一的样本，第二个参数“10”可以忽略!

希望能有所帮助!

很多答案都忽略了一点(至少在Windows中)，如果ping命令收到“目标主机不可达”的回复，它将返回0(表示成功)。

下面是我的代码，它检查b' ttl ='是否在响应中，因为它只在ping到达主机时才出现。注意:此代码的大部分是基于这里的其他答案。

import platform
import subprocess

def ping(ipAddr, timeout=100):
    '''
    Send a ping packet to the specified host, using the system ping command.
    Accepts ipAddr as string for the ping destination.
    Accepts timeout in ms for the ping timeout.
    Returns True if ping succeeds otherwise Returns False.
        Ping succeeds if it returns 0 and the output includes b'TTL='
    '''
    if platform.system().lower() == 'windows':
        numFlag = '-n'
    else:
        numFlag = '-c'
    completedPing = subprocess.run(['ping', numFlag, '1', '-w', str(timeout), ipAddr],
                                   stdout=subprocess.PIPE,    # Capture standard out
                                   stderr=subprocess.STDOUT)  # Capture standard error
    # print(completedPing.stdout)
    return (completedPing.returncode == 0) and (b'TTL=' in completedPing.stdout)

print(ping('google.com'))

注意:这将捕获输出而不是打印输出，因此如果您希望看到ping的输出，则需要打印completedPing。返回前的Stdout。

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"))

我需要一个更快的ping扫描，我不想使用任何外部库，所以我决定使用内置的asyncio来实现并发。

此代码需要python 3.7+，仅在Linux上制作和测试。它不能在Windows上工作，但我相信你可以很容易地将其更改为在Windows上工作。

我不是asyncio方面的专家，但我使用了这篇很棒的文章，用并发性加速你的Python程序，我想出了这些代码行。我试图使它尽可能简单，所以很可能您需要添加更多的代码来满足您的需求。

它不会返回true或false，我认为让它打印响应ping请求的IP会更方便。我认为这是相当快的，在近10秒内ping 255个ip。

#!/usr/bin/python3

import asyncio

async def ping(host):
    """
    Prints the hosts that respond to ping request
    """
    ping_process = await asyncio.create_subprocess_shell("ping -c 1 " + host + " > /dev/null 2>&1")
    await ping_process.wait()

    if ping_process.returncode == 0:
        print(host)
    return 


async def ping_all():
    tasks = []

    for i in range(1,255):
        ip = "192.168.1.{}".format(i)
        task = asyncio.ensure_future(ping(ip))
        tasks.append(task)

    await asyncio.gather(*tasks, return_exceptions = True)

asyncio.run(ping_all())

样例输出:

192.168.1.1
192.168.1.3
192.168.1.102
192.168.1.106
192.168.1.6

请注意，IP不是按顺序排列的，因为IP在它响应时就会打印出来，所以先响应的就会先打印出来。
