Any program that runs has a concept of a "current directory". All its
work is done relative to that, unless you open files with absolute

Don't know if there's a generic way to do what you want. (There may
be, just can't think of it right now). But there are specific ways -
script-specific, that is:

Add these lines to the top of your script:

import os

# Replace rundir above with the absolute path (in quotes) of whatever
directory you want the script to have as its current directory when it

Looks like GNOME is doing a chdir to your home directory (probably for
convenience or security reasons) before running your script, thats why
you see that behaviour. This is why I say there may not be an easy
generic way to do it - because it would involve modifying all possible
execution environments from which your script could be launched. E.g.:
even if you modify GNOME to do what you want, how about if tomorrow
someone else wants to run your script from KDE or some other window
manager? these could do things differently.
