I don't -- I just use TextWrangler and a Terminal window.  I tried 
several IDEs and didn't really find any of them stable and feature-rich 
enough to be worth the bother (though Editra came close).

Lack of a really top-notch IDE is one of the primary drags harshing on 
my Python buzz (as the young people say).

Best,
