What are standard and better ways? You could explore the performance of popping items from the dict/set, instead of toggling the value so to true. Once the dict is empty, you are done. Of course the dict/set would be called stocks_that_havent_reported, or a saner & shorter variant of that. The idea here is that checking a dict/set for emptiness is close-to-zero time operation. -- http://mail.python.org/mailman/listinfo/python-list
