Yes, or if you prefer what python prints is the decimal notation of the number.

Those notaional strings end up being printed. As I said before we are so used in using the decimal notation that we often use the notation and the number interchangebly without a problem. But when we are working with multiple notations that can become confusing and we should be careful to seperate numbers from their representaions/notations. > but when we need a decimal integer There are no decimal integers. There is only a decimal notation of the number. Decimal, octal etc are not characteristics of the numbers themselves. -- Antoon Pardon -- http://mail.python.org/mailman/listinfo/python-list
