Python IDE

[VanL]

FWIW, Scite (http://scintilla.org/) has been all I wanted in 
an python editor/ide for a while.  Well, maybe not *all* I 
wanted, but its close.

Free, code folding, syntax highlighting, one click (or one 
hotkey) execution in second pane, cross-platform, 
lightweight (fits on a floppy).

What is missing: integrated debugger (you must use pdb for 
debugging if you want to do it within the editor/ide 
environment) and an integated python console.
