Calculating pi with a certain precision?

Question

Python

The formula/code for a subject is necessary.
I read that there is a Gauss formula (high calculation speed), but I could not google it. In general, what exactly will be used is not so critical, but I would like to see the implementation of the Gauss formula.
It will be used in Python3 code, so I will be grateful if someone shares a ready-made solution.

Answer 1

Is that not it?

Answer 2

Yandex rules: algolist.manual.ru/maths/count_fast/pi.php
At the bottom of the page there is a C++ example for the Gauss formula.
