Hi, 

The subprocess method of python should be use only when there is no other 
alternative. we can avoid using it to find state of the interface.

use cat /sys/class/net/eth0/operstate and python file I/O instead of ip link 
show command to get the sate of the device or to list the devices that are 
available.
