I haven't got literature but I've got a (hopefully straightforward) explanation: In binary 2 is 10. When you multiply by 10, you shift all your digits left by 1 place. When you multiply by 10**n (which is 1 followed by n zeroes), you shift all your digits left by n places. HTH -- Arnaud -- http://mail.python.org/mailman/listinfo/python-list
