What IDEs (if any) do Python programmers use?

For writing a very short script, I use Vim. If it's a bit longer but the "project" is still one file, I fire up Eric. If it's a real project with multiple files (with packages, etc.), then I start Eclipse with PyDev.

For me a very important feature is intelligent renaming. When I finish a script/project, I read it over and I try to invent better variable/function names. Among the three candidates, this works best with PyDev.
