Answer 1

import subprocess
process = subprocess.Popen(command, shell=True, stdout=subprocess.PIPE)
process.wait()
print process.returncode

The command variable should be for example: cmd /k. You can also add a stdin=subprocess.PIPE to the Popen argument list and write commands to cmd: subprocess.Popen(command, shell=True, stdout=subprocess.PIPE,stdin=subprocess.PIPE) the final code:

import subprocess
process = subprocess.Popen('cmd /k ', shell=True, stdin=subprocess.PIPE,stdout=subprocess.PIPE,stderr=None)
process.stdin.write("dir") #passing command
stdOutput,stdError = process.communicate()
print stdOutput
process.stdin.close()

Or alternatively:

from subprocess import *
Popen("cmd /k dir")
