Is this a typo you do not need the .py on the end
it should (perhaps) read:

from library import function

The pythonpath (or PYTHONPATH) variable is an environment variable - 
I'm no MAC expert but I expect there is a command you could use to show
it's value... however from inside a running python program the
PYTHONPATH variable is stored in  sys.path and is a list of paths that
python will look in for your module / package.

A quick google on PYTHONPATH should point you towards some useful
information... it is also explained in the (free, online) python
tutorial 
http://www.python.org/doc/current/tut/node8.html#SECTION008110000000000000000
