You may use this recipe of mine that I've just put there for you, but it's not fully tested yet (if you spot problems I'm willing to fix them): http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/502295 Or you can create a little class, that wraps your list with just a __cmp__ method that works on the n-th element of the list. Then you can use heapq on many instances of that class created with a list comphrension. Probably there are other solutions too. Bye, bearophile -- http://mail.python.org/mailman/listinfo/python-list
