Multi-threading isn't part of Fortune's algorithm. Multi-threading can be confusing, but it's better for you to learn to feel at home using hash maps (named dicts in Python), because they are both essential in computer science and in Python. Ask if you need some help regarding dicts and sets. Bye, bearophile -- http://mail.python.org/mailman/listinfo/python-list
