The best platform and editor for Python

[ed]

for my part, i'm a big fan of DrPython for writing python
code (especially on windows).
http://drpython.sourceforge.net/

you will need wxPython to have it running though

 It's not per se an IDE but it
has a lot of feature to help you writing with some interesting plug-
ins.
You can launch code in the IDE, you have an inserted console etc.

Oh and it's written in python :)
