Does anyone know of any good books for people that are proficient with Python and want to learn more about the language and come closer to being an expert?<p>The idea of LPTHW has always seemed cool, but I've looked at the table of contents a couple of times and thought "huh, 80% of these topics seem trivial to me"; maybe I could still benefit by skimming through and reading anything that I don't already know. Also, it's kind of a bummer that there's no .mobi version.
