In addition to what others have said, it looks like you're designing your
script to run as root. This is a Very Bad Idea(tm) and has the potential to
destroy your system if you make a minor mistake and end up blowing away vital
system files.
If you want to be able to run the script anywhere but have the results saved in
your home directory, then look into calling os.path.expanduser('~/Desktop') to
write to the Desktop directory in your home directory.
