subprocess.call("date")

after the execution

Traceback (most recent call last):
 File "<stdin>", line 1, in <module>
 File "C:\Python27\lib\subprocess.py", line 168, in call
 return Popen(*popenargs, **kwargs).wait()
 File "C:\Python27\lib\subprocess.py", line 390, in __init__
 errread, errwrite)
 File "C:\Python27\lib\subprocess.py", line 640, in _execute_child
 startupinfo)
WindowsError: [Error 2] The system cannot find the file specified

Answer 1

You must do this:

subprocess.call('date', shell=True)

Actually, Shell does allow you to access to global variable and programs that are in $PATH and your shell.

Answer 2

Have you tried ?

import subprocess
subprocess.call("date", shell = True)
