Step 3: Verify Installation

1. Open the Terminal app.

2. Type python3 --version and press Enter to check if the latest version is installed.

Optional: Install Homebrew

If you prefer using a package manager, you can install Python via Homebrew:

1. Install Homebrew by running the following command in Terminal:

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

2. Once Homebrew is installed, use this command to install Python:

brew install python

3. Installing Python on Linux

Linux users typically have Python pre-installed. However, you might need to update or install a newer version. Here’s how to do it:

Step 1: Check for Pre-installed Python

1. Open the Terminal.

2. Type python3 --version and press Enter to check if Python is installed and to verify the version.

Step 2: Install Python Using Package Manager

Most Linux distributions have Python available in their package repositories. Use the following commands based on your distribution:

For Ubuntu/Debian:

sudo apt update  
sudo apt install python3

For CentOS/Fedora:

sudo yum install python3

For Arch Linux:

sudo pacman -S python

Step 3: Verify Installation
