Shrug. When you "print" a number, Python transcribes a string
representation of it to your terminal.

Yep. Same thing. A "notation" is a particulart formal method of
representation.

Everything you see like that is textual information. Internally to
Python, various types are used: strings, bytes, integers etc. But
when you print something, text is output.
