If you need exact values, gmpy (http://code.google.com/p/gmpy/) has basic, but fast, support for calculating binomial coefficients and factorials. If you are floating point approximations, check out mpmath (http://code.google.com/p/mpmath/). casevh -- http://mail.python.org/mailman/listinfo/python-list
