PyJudy might be what you're looking for, though I've never used it: http://www.dalkescientific.com/Python/PyJudy.html "Judy's key benefits are scalability, high performance, and memory efficiency. A Judy array is extensible and can scale up to a very large number of elements, bounded only by machine memory." ... "PyJudy arrays are similar to Python dictionaries and sets." -- Richie Hindle [EMAIL PROTECTED] -- http://mail.python.org/mailman/listinfo/python-list
