How is this called? s = s.splitlines()

ok, thank you.

But let’s take another example:
x = x + 1
in programming language it is assignment, variable binding…

But in mathematics x = x+1 is non-sense.

The Functional programming paradigm is closer to mathematics. So how would a functional style of incrementing look like?

(btw. when speaking about incrementing, I would love to have something like inc(x) function that simply increments x.
Is there something like that?)

EDIT: I have created a separate thread about increment/decrement here: Increment, decrement... Can we have inc(), dec() functions in Python? feature request :)
