The code and error below has nothing to do with importing modules or the 
PYTHONPATH value.

This is simply opening the file module.py as any other file.
It does not invoke Pythons import mechanism.

Please post the full error text not a summary.
But in this case it isc complaining about the favct that you have not 
put quotes around the filename so it thinks module.py is a variable, but 
when it looks for it, it is not defined.

BTW To set PYTHONPATH in a MacOSX environment you have to edit your 
.profile or .bash_profile (I can never remember which!) and add a line like

export PYTHONPATH=/path/to/your/modules:/another/module/path/here
