^ is the "bit XOR" operation. It treats its left and right operands as binary numbers: the result has a one-bit in those bit positions where one operand has a zero and the other has a one. A B | A XOR B ----+-------- 0 0 | 0 0 1 | 1 1 0 | 1 1 1 | 0 If you want exponentiation, try **. >>> 3**4 81 >>> 3**5 243 >>> 3**6 729 >>> 3**7 2187 >>> regards Steve -- Steve Holden +44 150 684 7255 +1 800 494 3119 Holden Web LLC www.holdenweb.com PyCon TX 2006 www.pycon.org -- http://mail.python.org/mailman/listinfo/python-list
