IDEs with introspection-based code completion and integrated debugger

Name	Platform	Updated	Notes
["Komodo"]	Windows/Linux/Mac OS X	2008	Multi-language IDE. Available as Komodo IDE (commercial) and Komodo Edit (open source, as part of the OpenKomodo project) [Note: This seems to be totally incorrect - Komodo Edit is closed-source, and is not part of the OpenKomodo project. The first usable application from OpenKomodo looks like it will be called "Komodo SnapDragon", but it is unclear if that will have any Python support at all.]
PyDev	Eclipse	2008	Open source plugin for Eclipse -- Allows Python and Jython Editing, code-completion, debugger, refactoring, templates, syntax analysis, etc.; see also [http://www.fabioz.com/pydev PyDev Extensions]
