Installing and running Redis on macOS can be done in several ways, including using Homebrew (a package manager for macOS), downloading and compiling from source, or running it as a Docker container. The simplest method for most users is via Homebrew.

Installing Redis with Homebrew:

1. Install Homebrew: If you don't already have Homebrew installed on your Mac, open the Terminal app and run the following command. This script installs Homebrew itself.

   /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

Getting started with Python on a Mac with an M1 chip is a straightforward process. Below, I'll guide you through the steps to set up Python, create a simple "Hello, World!" program, and run it to see the output.

Step 1: Check Python Installation

macOS comes with Python pre-installed, but it's usually Python 2.7. Since you'll want to use Python 3, you should first check if it's already installed:

1. Open the Terminal app (you can find it using Spotlight search by pressing Cmd + Space and typing "Terminal").
2. Type python3 --version and press Enter. If you see a version number (e.g., Python 3.x.x), Python 3 is installed. If not, you'll need to install it.
