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)

此函数适用于任何操作系统(Unix、Linux、macOS和Windows) Python 2和Python 3

编辑: @radato os。System被subprocess.call取代。这避免了在没有验证主机名字符串的情况下shell注入漏洞。

import platform    # For getting the operating system name
import subprocess  # For executing a shell command

def ping(host):
    """
    Returns True if host (str) responds to a ping request.
    Remember that a host may not respond to a ping (ICMP) request even if the host name is valid.
    """

    # Option for the number of packets as a function of
    param = '-n' if platform.system().lower()=='windows' else '-c'

    # Building the command. Ex: "ping -c 1 google.com"
    command = ['ping', param, '1', host]

    return subprocess.call(command) == 0

注意，根据Windows上的@ikrase，如果你得到一个目标主机不可达错误，这个函数仍然会返回True。

解释

该命令在Windows和类unix系统中都是ping。 选项-n (Windows)或-c (Unix)控制包的数量，在本例中设置为1。

platform.system()返回平台名称。前女友。macOS上的“达尔文”。 Subprocess.call()执行一个系统调用。例如subprocess.call ([' ls ', ' - l '])。

  1 #!/usr/bin/python
  2
  3 import os
  4 import sys
  5 import time
  6
  7 os.system("clear")
  8 home_network = "172.16.23."
  9 mine = []
 10
 11 for i in range(1, 256):
 12         z =  home_network + str(i)
 13         result = os.system("ping -c 1 "+ str(z))
 14         os.system("clear")
 15         if result == 0:
 16                 mine.append(z)
 17
 18 for j in mine:
 19         print "host ", j ," is up"

一个简单的我只是在一分钟内煮出来的..使用icmplib需要根privs下面的工作非常好! HTH

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

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"))
