Lazy me never bothered to use proper indent/dedent function, since TAB will cycle through indentation levels.. but I'm happy I read your comment since cycling isn't efficient.

ps: although it seems, vanilla python mode binds them to 'C-c >' and 'C-c <'

Just like monads, sexps have that curse when you get how paredit or alikes work, you just can't explain how awesome it is to non lispers.
