Python module import failed error

[matt . doolittle33]

Hello all; I am using Ubuntu 12.10 and Python v2.7.3.  I am trying to add a 
directory to the PYTHONPATH.  All of the commands I have found on the web have 
failed.  Please help me to add a directory to the PYHONPATH.  The file path is 
Home/home/bin.  Thanks in advance.
