How to create a file one directory up?

How can I create a file in python one directory up, without using the full path?

I would like a way that worked both for windows and linux.

Thanks.

People don't seem to realize this, but Python is happy to accept forward slash even on Windows. This works fine on all platforms:

fobj = open("../filename", "w")

Depends whether you are working in a unix or windows environment.

On windows:

..\foo.txt

On unix like OS:

../foo.txt

you need to make sure the os sets the current path correctly when your application launches. Take the appropriate path and simply create a file there.

Use os.pardir (which is probably always "..")

import os
fobj = open(os.path.join(os.pardir, "filename"), "w")
