Ok here you go, the "walrus operator" is
actually a good lead, we have that this
here from JavaScript:

    x++

    respectively

    ++x

Can be replaced by the Python expression:

    (x := x + 1) - 1

    respectively

    (x := x + 1)

Here is a test only testing x++:

Python 3.14.0a1 (tags/v3.14.0a1:8cdaca8, Oct 15 2024, 20:08:21)
 >>> x = 5
 >>> (x := x + 1) - 1
5
 >>> x
6
