Don't change the library modules. It would catch you anytime when you
expect it least.

See for the environment variable PYTHONSTARTUP and the associated
startup file.

sitecustomize.py would be a better place. PYTHONSTARTUP is only used when
running in interactive mode.
Anyway, I'd do that explicitely on each script that requires it; after
upgrading the Python version, or moving to another PC, those scripts would
start failing...

If you pass a relative pathname to open() (or any other function which
expects a filename), it will be interpreted relative to the current
directory.

Given that the current directory always seems to be the Python directory,
and you refer to it as a "folder", I'm guessing that you're running Python
on Windows via a shortcut in the Start Menu or on the desktop.

In which case, the ideal solution is probably to open the Properties
dialog for the shortcut and change the "Start in" field to your
"My Documents" directory (or some subdirectory of it).

Python itself won't care which directory it starts in.

from os.path import join
BASE = '/path/to/root'
f = open(join(BASE, filename))

Trust me, you'll be much happier with this.
