确保安装了pyping或安装它

#!/usr/bin/python
import pyping

response = pyping.ping('Your IP')

if response.ret_code == 0:
    print("reachable")
else:
    print("unreachable")

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

#!/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()

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

我有类似的要求，所以我实现它如下所示。它在Windows 64位和Linux上进行了测试。

import subprocess
def systemCommand(Command):
    Output = ""
    Error = ""     
    try:
        Output = subprocess.check_output(Command,stderr = subprocess.STDOUT,shell='True')
    except subprocess.CalledProcessError as e:
        #Invalid command raises this exception
        Error =  e.output 

    if Output:
        Stdout = Output.split("\n")
    else:
        Stdout = []
    if Error:
        Stderr = Error.split("\n")
    else:
        Stderr = []

    return (Stdout,Stderr)

#in main
Host = "ip to ping"
NoOfPackets = 2
Timeout = 5000 #in milliseconds
#Command for windows
Command = 'ping -n {0} -w {1} {2}'.format(NoOfPackets,Timeout,Host)
#Command for linux 
#Command = 'ping -c {0} -w {1} {2}'.format(NoOfPackets,Timeout,Host)
Stdout,Stderr = systemCommand(Command)
if Stdout:
   print("Host [{}] is reachable.".format(Host))
else:
   print("Host [{}] is unreachable.".format(Host))

当IP不可达时，subprocess.check_output()将引发异常。额外的验证可以通过从输出行“Packets: Sent = 2, Received = 2, Lost = 0 (0% loss)”中提取信息来完成。

有一个名为pyping的模块可以做到这一点。可以用pip安装

pip install pyping

它使用起来非常简单，但是，当使用这个模块时，您需要root访问权限，因为它在底层制作原始数据包。

import pyping

r = pyping.ping('google.com')

if r.ret_code == 0:
    print("Success")
else:
    print("Failed with {}".format(r.ret_code))
