These kind of variables (PYTHONPATH, PERL5LIB, CLASSPATH, ...) are 
normally unset unless someone initializes them.

If your shell is bash, put in ~/.bashrc the line

     export PYTHONPATH=/Users/simonforster/Development/Python/Lib

in zsh that goes in ~/.zshenv. Other shells use other rc files.

Once you've done that there's no need in general to modify sys.path 
from the very script.

-- fxn

PS: You'll need to source the rc file or open a new Terminal.app to 
make the initialization effective.
