title: How to assign IP address to interface in python?
body: <p>I have python script that set the IP4 address for my wireless and wired interfaces. So far, I use <code>subprocess</code> command like :</p>
  
  <pre><code>subprocess.call(["ip addr add local 192.168.1.2/24 broadcast 192.168.1.255 dev wlan0"])
  </code></pre>
  
  <p>How can I set the IP4 address of an interface using python libraries? 
  and if there is any way to get an already existing IP configurations using python libraries ? </p>
