use Eclipse!!! it is not a editor but it is the best free IDE out there. for python use Pydev(pydev.sf.net) plugin:it got EVERYTHING:completteion,debuging(with thread support)you can`t work without a debugger for serious projects. for Web Develop use Aptana(aptana.com) another plugin for eclipse,in eairly stages but it is very amazing support most of open source javascript library with auto-complete and outline of code. Scribes look very nice for a editor i will try it for lightweight editing.
