How do I install Python 3 on my Mac?

Answered by Jason Smith

To install Python 3 on your Mac, you will need to follow a few steps. Before proceeding with the installation, make sure you have a stable internet connection and some free disk space on your Mac.

1. Install Xcode:
The first step is to install Xcode, which is Apple’s Integrated Development Environment (IDE). Xcode includes the necessary tools and libraries required for building software on Mac. You can download Xcode from the Mac App Store or Apple’s developer website. Once downloaded, follow the installation instructions to complete the process.

2. Install Homebrew:
Homebrew is a popular package manager for macOS that allows you to easily install and manage various software packages. To install Homebrew, open Terminal (you can find it in the Utilities folder within the Applications folder) and paste the following command:

/bin/bash -c “$(curl -fsSL”

Press Enter and follow the prompts to complete the installation. Homebrew will install necessary dependencies and set up the required directories.

3. Install Python 3 with Homebrew:
Once Homebrew is installed, you can use it to install Python 3. Open Terminal again and enter the following command:

Brew install python3

Press Enter and Homebrew will start downloading and installing Python 3 and its related packages. This process may take a few minutes, depending on your internet speed.

4. Verify the installation:
After the installation is complete, you can verify that Python 3 is installed correctly by running the following command in Terminal:

Python3 –version

This command will display the version of Python 3 installed on your Mac. If you see the version number, it means Python 3 is successfully installed.

5. Optional: Configure PATH environment:
By default, Homebrew installs Python 3 to `/usr/local/bin/python3`. It’s recommended to add this directory to your PATH environment variable, allowing you to run Python 3 from anywhere in the Terminal. To do this, open Terminal and enter the following command:

Echo ‘export PATH=”/usr/local/bin:$PATH”‘ >> ~/.bash_profile

This command appends the necessary export statement to your `.bash_profile` file, which is a script that runs every time you open Terminal. After executing the command, restart Terminal or run `source ~/.bash_profile` for the changes to take effect.

That’s it! You have successfully installed Python 3 on your Mac using Homebrew. You can now start using Python 3 for various programming tasks, including writing scripts, developing applications, or working on data analysis projects.

Please note that as macOS updates are released, the installation process may slightly vary. It’s always a good idea to refer to the official documentation or community resources if you encounter any issues during the installation process.
