Python - obtener la ip y mascara de red procesando la salida del comando ifconfig

import subprocess

subprocess.call(["ifconfig","wlp8s0"])

import subprocess

import re

result=subprocess.Popen(["ip", "address", "show", "dev", "eth0"], stdout=subprocess.PIPE)

cadena=str(result.communicate()[0])

ip=re.findall("inet [0-9]{,3}\.[0-9]{,3}\.[0-9]{,3}\.[0-9]{,3}",cadena)

if ip and len(ip[0].split())==2:

    print(ip[0].split()[1])

import subprocess

output = subprocess.check_output(["ip", "address", "show", "dev", "eth0"])
