How does print(*x + y) work?

Question

Python

Good afternoon!
Studying Lutz and experimenting on his advice, including unpacking through an asterisk, I discovered a strange construction, and I don’t quite understand how it works and why?
Namely:

x = (1, 2, 3)
y = (4, 5, 6)
print(*x + y)

More precisely, I suspect that x and y are added first, and then the total is unpacked. But why does it work the way it does? What rule makes tuple addition work first, and then unpacking?

Answer 1

Tuple addition rule) x + y is essentially a new tuple that is unpacked
