system cannot find the specified file python subprocess -


i trying run simple command in python:

from subprocess import *     check_output("ls")

when run raises 

error: windowserror: [error 2] system cannot find file specified

ls doesn’t exist on windows; dir does. furthermore, may need pass shell=true, since it’s built in cmd.exe.

if it’s not test , want contents of directory, use os.listdir instead.
