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

No it wouldn't, You are confusing representation in the everyday meaning
with representation as python jargon.


> Python prints numbers:
No it doesn't, numbers are abstract concepts that can be represented in
various notations, these notations are strings. 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.
