# This script automates the setup of an Amazon EC2 instance for managing Google Workspace accounts using GAMADV-XTD3 and AWS QuickSight.
# It performs the following functions:
# 1. Updates the system and installs Python along with necessary dependencies.
# 2. Optionally sets up Python and pip aliases for convenience.
# 3. Installs or updates the AWS CLI and allows the user to configure the AWS region.
# 4. Installs or updates GAMADV-XTD3, a command-line tool for Google Workspace administration.
# Usage: Run this script as a superuser on an Amazon EC2 instance to prepare the environment for Google Workspace and AWS management.
