When Python sees (True and False) it first evaluates True, which is obviously True. Because the first argument was not False, it continues on and evaluates False. At this point Python stops evaluating anything else (for example if you had (True and False and True)) and returns False, which is then negated by 'not'. -- Jack Trades Pointless Programming Blog <http://pointlessprogramming.wordpress.com>
