Simple speed tests for Python 3.11

Speed test for Python 3.11

I created a simple speed test to compare Python 3.11 to 3.10 (and 3.9 .. 3.5). The tests use a Monte Carlo Pi estimation. This is probably not the best workload for a full Python stress test.

Run original test using Docker

Requirements

• Python environment to run the tester
• Docker to download each Python Env.

Usage:

cd pi_estimates/Python
python run_main_test.py
