title: How to associate py extension with python launcher on Mac OS X?
body: <p>Does anyone know how to associate the py extension with the python interpreter on Mac OS X 10.5.7? I have gotten as far as selecting the application with which to associate it (/System/Library/Frameworks/Python.framework/Versions/2.5/bin/python), but the python executable appears as a non-selectable grayed-out item. Any ideas?</p>
