The Python Standard Library By Example - Doug Hellmann. For all those who prefer a printed version of the internet: this is a book with all the PyMOTW (Python Module of the Week) articles in it, polished and beautified and nicely compiled. Certainly very practical, because sometimes you have a book quicker at hand than a computer - and computers are forbidden in bed anyway. (Warning: regarding bed, this is a 1344-page whopper!).
