- From $ZOPE/lib/python/ZTUtils/Iterator: __doc__='''Iterator class Unlike the builtin iterators of Python 2.2+, these classes are designed to maintain information about the state of an iteration. The Iterator() function accepts either a sequence or a Python iterator. The next() method fetches the next item, and returns true if it succeeds. $Id: Iterator.py,v 1.9.42.2 2003/11/04 19:27:43 evan Exp $''' Note that last sentence, which explains why you are seeing the '1' value everywere. 'tal:repeat' over a range should get you what you want; I don't think you *need* an iterator for your use case.
