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 '])。

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'

样例输出

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!

我借鉴了其他答案。尝试简化和最小化查询。

import platform, os

def ping(host):
    result = os.popen(' '.join(("ping", ping.param, host))).read()
    return 'ttl=' in result.lower()

ping.param = "-n 1" if platform.system().lower() == "windows" else "-c 1"

编辑:根据奥利维尔B的评论，忽略返回的大小写。

import os #to get clear screen
import subprocess as sp #to get system ping
os.system("clear") #clear screen
print('Wait or Press Ctrl+Z to Terminate\n') #notice to terminate or wait
for i in range(255): #0 to 255 loop
    ip='192.168.1.'+str(i) #concatenating str and int
    s,r=sp.getstatusoutput("ping -c1 -w2 " + ip) #ping and store status in s
    if s==0: #if status is 0 equal to pass
        print(ip+" is UP ✓ ") #output
    else: #if status is not 0 equal to fail
        pass #skip and try next ip from loop

编程ICMP ping很复杂，因为发送原始ICMP包需要更高的权限，而且调用ping二进制很难看。对于服务器监控，您可以使用TCP ping技术实现相同的结果:

# pip3 install tcping
>>> from tcping import Ping
# Ping(host, port, timeout)
>>> ping = Ping('212.69.63.54', 22, 60)
>>> ping.ping(3)
Connected to 212.69.63.54[:22]: seq=1 time=23.71 ms
Connected to 212.69.63.54[:22]: seq=2 time=24.38 ms
Connected to 212.69.63.54[:22]: seq=3 time=24.00 ms

在内部，这只是建立一个到目标服务器的TCP连接，并立即丢弃它，测量所消耗的时间。这个特殊的实现有点局限，因为它不能处理封闭的端口，但对于您自己的服务器来说，它工作得很好。
