Is there a way I could send commands to Windows command prompt Python?

What I am looking to do is make a Python app on the desktop which receives commands through sockets from another computer/mobile app.

These commands are then passed on to Windows command prompt for execution.

Using Windows 7.

Do you mean the real MS-DOS, or the Windows Command Prompt? (The latter is not DOS. It's a Windows program.) – grawity Dec 23 '10 at 12:03
Windows command prompt.. – Akash Dec 23 '10 at 12:10
are you just interested in execution, do not care how it works behind the scenes or do you really need the console (cmd.exe)? – akira Dec 23 '10 at 18:51
@akira: terminology - cmd.exe is a shell, it parses commands. A console displays them and their output on screen. – grawity Dec 23 '10 at 20:46

use subprocess module

from subprocess import call

call(['cmd', 'arg1', 'arg2'], stdin='...', stdout='...')


call(['dir', '/W'])

Sometimes, os.system can be a better choice - for example, if you have a complete command line and do not want to modify it (which Akash's question seems to be like.) – grawity Dec 23 '10 at 13:27
@grawity: subprocess.Popen() and there you have os.system() – akira Dec 23 '10 at 18:49
@akira: My point was about os.system("dir /w") versus call(["dir", "/w"]) - splitting the input just to have it rejoined later, and execution via shell. Although I was wrong - I forgot about Popen(..., shell=True), which does accept a string command. – grawity Dec 23 '10 at 20:44
