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。

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)

#!/usr/bin/python3

import subprocess as sp

def ipcheck():
    status,result = sp.getstatusoutput("ping -c1 -w2 " + str(pop))
    if status == 0:
        print("System " + str(pop) + " is UP !")
    else:
        print("System " + str(pop) + " is DOWN !")


pop = input("Enter the ip address: ")
ipcheck()

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

            break
        else:

    else:
        print('timed out')

def encode(payload: bytes):
    # calculate checksum with check set to 0
    checksum = calc_checksum(icmp_header(ICMP.ECHO_REQUEST, 0, 0, 1, 1) + payload)

    return icmp_header(ICMP.ECHO_REQUEST, 0, checksum, 1, 1) + payload

WINDOWS ONLY -不敢相信没有人破解Win32_PingStatus 使用一个简单的WMI查询，我们可以免费返回一个包含非常详细信息的对象

import wmi


# new WMI object
c = wmi.WMI()

# here is where the ping actually is triggered
x = c.Win32_PingStatus(Address='google.com')

# how big is this thing? - 1 element
print 'length x: ' ,len(x)


#lets look at the object 'WMI Object:\n'
print x


#print out the whole returned object
# only x[0] element has values in it
print '\nPrint Whole Object - can directly reference the field names:\n'
for i in x:
    print i



#just a single field in the object - Method 1
print 'Method 1 ( i is actually x[0] ) :'
for i in x:
    print 'Response:\t', i.ResponseTime, 'ms'
    print 'TTL:\t', i.TimeToLive


#or better yet directly access the field you want
print '\npinged ', x[0].ProtocolAddress, ' and got reply in ', x[0].ResponseTime, 'ms'

在windows或linux中Ping它们，返回一个排序的列表。这是@Ahmed Essam和@Arno回复的混合/修正。
