Ok, that either means I need to upgrade to 3.3 or need to modify the snippet to a suitable syntax that would work with other versions. Considering that upgrading is something that I'm not keen to do on my production system I believe I've only have one available choice. It seems I could use the generator and iterate with .next() in python 2.6, at least from what I found here: http://stackoverflow.com/questions/1756096/understanding-generators-in-python Al -- https://mail.python.org/mailman/listinfo/python-list
