How to Install Python 3 on macOS

Python is a powerful programming language, and macOS comes with Python 2.x pre-installed. However, it’s recommended to use Python 3 for modern development. Here’s a step-by-step guide to installing Python 3 on macOS.

Step 1: Check the Current Python Version

Before installing, check if Python 3 is already installed:

python3 --version

If you see something like Python 3.x.x, you already have Python 3. If not, proceed with the installation.

Step 2: Install Homebrew

Homebrew is a popular package manager for macOS, making it easy to install software like Python. If you haven’t installed Homebrew yet, run this command:

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

After installation, ensure Homebrew is set up correctly:

brew --version

Step 3: Install Python 3

Use Homebrew to install Python 3:

brew install python3

Once the installation is complete, verify it:

python3 --version

Step 4: Set Up Your Environment
