title: Where can I find the source for "python mode" when editing emacs configuration for mac os x?
body: <p>I'm looking to play with python mode for emacs on mac os x, but I can't seem to find the source files for the mode.</p>
  
  <p>What are the standard locations, where a default installation of emacs might have put its modes when installed on Mac OS X?</p>
  
  <p>(I'm using GNU Emacs 24.0.95.1 (i386-apple-darwin11.3.0, NS apple-appkit-1138.32))</p>
