To test:
Create a test.sh file in any directory
Paste the requested changes into the file:

#!/bin/bash

# Define the Python download URL prefix
PYTHON_DOWNLOAD_URL_PREFIX="https://www.python.org/ftp/python"

# Fetch the list of available Python versions
VERSION_LIST=$(curl -s "$PYTHON_DOWNLOAD_URL_PREFIX/" | grep -oP '(?<=href=")[0-9]+\.[0-9]+\.[0-9]+(?=/")')

# Filter out non-stable versions (e.g., alphas, betas, release candidates)
STABLE_VERSIONS=$(echo "$VERSION_LIST" | grep -E '^[0-9]+\.[0-9]*[02468]\.[0-9]+$')

# Get the latest stable version
LATEST_STABLE_VERSION=$(echo "$STABLE_VERSIONS" | sort -V | tail -n 1)

echo $LATEST_STABLE_VERSION

Change file permissions chmod +x test.sh
Run the file from the command line ./test.sh

Expected result:
You should see the latest stable Python version number
