I recently stumbled across the RopeMate bundle for TM. For Python it gives you intellisense/code-sense style autocompletion, and also a nifty 'refactor' command (ie. pull the selected code out into a new function which accepts any referenced variables as arguments), replacing the existing code with a call to the new function. Highly recommended.
