Best Python IDE Code Completion!

[John]

Hi,
  Could you give your opinions on the best code completion in Python
IDEs. My only complaint with PythonWin has been that the code
completion support is incomplete. The interactive mode has better
behavior than the editor. Tried to fix it but could not. Boa is not
too different. At least when I last checked (a few months ago) Komodo
and Visual Python were not very different either.

  Wing IDE seems converse. The editor auto list members is great but
has no calltips. The interactive window has no completion at all.

  I have not checked PythonWorks and Black Adder in a while but their
web sites do not seem to brag much in this direction.

  Python has great introspective capabilities and we have a great open
contributing community. What technical difficulties keep us from
having REAL code completion like MS, Borland and several Java IDEs
(All of which have been funded at one time or the other if not
entirely - perhaps this is the reason?)

  For me, code completion is a very important part of the coding
experience and I really miss it in Python in it's full effect.
