Embed windows or .cmd commands in a python script

To be able to execute external commands you must use one of the possibilities offered by subprocess . The recommended one is run () . I give you an example that I use, taking into account that the output is not captured.

import subprocess
#...
def cmd(commando):
    subprocess.run(commando, shell=True)

Example of use:

# Cambiar el título de la ventada de la consola
cmd('TITLE Título de la ventana')
# Ejecutar cmd externo
cmd('myscript.cmd parametro1 parametro2')

When using shell=True the parameters are passed as text. You can see it in more detail in this article from Chris Griffith .

If you are interested in reviewing what your code returns, you should use CompletedProcess .

def cmd(commando):
    resultado = subprocess.run(commando, shell=True)
    # Comprobar resultado, si es diferente de 0 lanza una excepción
    resultado.check_returncode()

Note: CompletedProcess is only available from Python 3.5
