Well better in what way? You now have to translate a predicate expression into a predicate function. Which AFAIU was one of the reasons to move away from map/filter to list comprehension. As I understand it, python made a move away from map and filter towards list comprehension. Chris seems to want some of the possibilities that came with that incorporated into the for statement. And your suggestion is to go back to the old kind of filter way. -- Antoon Pardon -- http://mail.python.org/mailman/listinfo/python-list
