if the script you're running is in the current directory, it'll just 
already do what you seem to be asking.

cd /home/davea/temppython
cat  peng.;py
import sys
print "sys.path is", sys.path

python peng.py
sys.path is ['/home/davea/temppython', '/usr/lib/python2.7', 
'/usr/lib/python2.7/plat-linux2', '/usr/lib/python2.7/lib-tk', 
'/usr/lib/python2.7/lib-old', '/usr/l .....

The text you quoted is trying to say that there are 3 different ways you 
can modify the search path.  The script name's location, the $PYTHONPATH 
environment variable, and the sys.path Python variable.
