How to extract the ip address and physical address a arp table for each device on a network in Pytho-CodePudding

I wrote this piece of code that displays the arp table on a network and it displays the information on multiple lines for each device on the network. I wanted to know if there was a way I can extract the IP Address and Physical Address for each device and as they are the only parts I need. Here are the codes I used to get the ARP table:

for device in os.popen('arp -a'):
    print(device)

I am fairly new to Python so I need help on how to get that information from the table we get when these codes are run.

CodePudding user response：

You can split the line on white space and keep the parts that interest you.

for device in os.popen('arp -a'):
    # example output: xxxx (192.168.1.254) at xx:xx:xx:xx:xx:xx [ether] on wlp..
    _, ip, _, phy, _ = device.split(maxsplit=4)
    # remove the paranthesis around the ip address
    ip = ip.strip('()')
    print(ip, phy)
