Shrug. When you "print" a number, Python transcribes a string
representation of it to your terminal.
>>> 16
16
So the output 16 is in fact a string representation of the number 16 ?
Then in what 16 and '16; differ to?

Yep. Same thing. A "notation" is a particulart formal method of
representation.
Can you elaborate please?

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.
Cheers,
Thanks!
