subprocess.Popen('start') fails

Question

Running this in python will result in a WindowsError stating it cannot find the specified file

FAILS:

import subprocess

subprocess.Popen('start notepad.exe')

In a command window, it works

start notepad.exe

Im guessing its a path thing where windows can't locate start[.exe?] Where is this located so i can add it in the path or just include it in the Popen call.

Thanks

I'm not entirely sure start is a program. I think it might be a built-in command of the CMD shell. Try

subprocess.Popen('cmd /c start notepad.exe')

Also, any reason why not use just:

subprocess.Popen('notepad.exe')
