Ask HN: High-signal sources for learning Python?

I have an interview for a Python developer position in a few days. I'm fairly confident about the algorithmic part, and have a generally wide knowledge of other relevant CS/programming areas, but I'd like to brush up on my Python.

Can you give me some _high-impact_ sources for learning Python? My idea of these sources is that they would approach (to some point) a trivia-list as their signal-to-noise ratio increases. I'm not looking for long-winded think-pieces about design patterns, reports about personal experience, or such, or rather large technical references, but something that had been pre-processed by a human, prioritized, etc.
