There's a fairly basic one in in MacPython IDE. This IDE apparently can 
also be made to work with a "macho" Framework build of Python, but 
that's not yet supported out-of-the box. Let me know off line if you 
need help with it (you can blame me for most everything that's wrong 
with it ;-), or CC me if you follow up to the group, as I read c.l.py 
fairly superficially these days... Unfortunately the IDE in the 2.2.1 
MacPython release still wants Mac-style line endings (returns), but you 
could grab the sources from CVS to fix that.
