Doug H. posted that he's working on a new series of articles around python development tools (everything from testing to syntax) to run in Python Magazine - I know he'll do a great job, so why don't you head over there and give him some feedback. Given this is coming hot on the heels of my analyzer post - I'm also interested to hear what people can't live without. (Noting of course there's a huge contingency of iPython people out there).
My personal list as of late is:
- Eclipse+Pydev (for bigger projects)
- Pychecker (with pylint coming up behind)
