   nullege is an interesting search Web application, with the
intelligence
   to distinguish between Python code and comments.  It provides what
   appear to be relevant results, and demands neither Java nor CSS be

   del.icio.us presents an intriguing approach to reference
commentary.
   It already aggregates quite a bit of Python intelligence.

   At least one of the Python magazines is explicitly multilingual:
       http://www.python.org/ar/

   PythonWare complemented the digest you're reading with the
   marvelous daily python url.  While it's now ... dormant, it still
   has plenty of interesting reading.
