CPython's sets are implemented in C. Old versions of Python implemented sets in the 'set' module which was written in Python but that has been deprecated and removed. A lot of the standard library is implemented in Python because it makes it more easily portable to non- CPython implementations. Chard. -- http://mail.python.org/mailman/listinfo/python-list
