Leave in zip(), enumerate(), and reversed(). They are meant to be used with listcomps and genexps. If you want to go the extra distance, itertools.izip() can offer a performance boost and better memory utilization than zip(). It can be used almost anywhere as long as the app doesn't demand a real list. Raymond Hettinger -- http://mail.python.org/mailman/listinfo/python-list
