Possible applications include bookmarking, windowing, or lookahead iterators. +\item A \function{basicConfig} function was added to the +\module{logging} package to simplify log configuration. It defaults +to logging to standard error, but a +number of optional keyword arguments can be specified to +log to a particular file, change the logging format, or set the +logging level.

The module already had \class{RotatingFileHandler}, +which rotated logs once the file exceeded a certain size. Both +classes derive from a new \class{BaseRotatingHandler} class that can +be used to implement other rotating handlers. + \item The \module{operator} module gained two new functions, \function{attrgetter(\var{attr})} and \function{itemgetter(\var{index})}. Both functions return callables that take a single argument and return the corresponding attribute or item; these callables make excellent -data extractors when used with \function{map()} or \function{sorted()}. -For example: +data extractors when used with \function{map()} or +\function{sorted()}.
