As a (reasonably) new Python programmer, what IDEs or editors would you recommend for Python programming on OS X and why (i.e. what features/capabilities/workflow techniques really help)? I've used Xcode and played a bit with TextMate but I can't really say that either have really hit the spot for me (although TextMate's code completion is pretty neat, I think i've been spoilt with code-completion facilities provided by editors for statically-typed languages so maybe i'm subconsciously comparing apples and oranges)

I'm looking to increase my efficacy with Python and any tips would be appreciated.

I know people have asked similar questions for Python IDEs in general but I am specifically concentrating on OS X and the 'Mac way'.

If Xcode or TextMate are thought highly of, perhaps some suggestions as to how I could get the most benefit from the tools would help.
