MKS command automation Python

Hi,

I am trying to automate MKS commands using python. Please help me to capture the error message.

Example:

import subprocess

import time

viewproject_cmd='im issues'
proc = subprocess.Popen(viewproject_cmd,stdout=subprocess.PIPE,shell=True)

(out, err) = proc.communicate()

The above script is throwing me following error,

*** MKS124814: Cannot show view information: MKS124808: This command requires operands: item id

I am unable to capture the above error in any variable. Also I see this error only if I execute the above python script in the cmd.exe

Please help me to handle the above error in python script itself.
