You don't. You should remember that python (or any programming language)
doesn't print numbers. It always prints string representations of
numbers. It is just so that we are so used to the decimal representation
that we think of that representation as being the number.

Normally that is not a problem but it can cause confusion when you are
working with mulitple representations.
