Different Methods to Get Python 3 on Mac
Method 1: Via Homebrew
Before you can install Python 3 using Homebrew, you need to have Homebrew installed on your Mac. If you don’t have it yet, you can download and install it by running the following command in your Mac’s Terminal:
`/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"`
Once Homebrew is installed, you can install Python 3 by running the following command in the Terminal:
`brew install python3`
Pros:
- Easy to install and maintain
- Provides access to the latest Python packages and libraries
- Ability to manage multiple Python environments
Cons:
- Requires Homebrew to be installed first
- May not be suitable for beginners
Steps:
1. Open Terminal on your Mac.
2. Install Homebrew by running the command `ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"`.
3. Verify that Homebrew is installed by running the command `brew doctor`.
4. Install Python 3 by running the command `brew install python3`.
5. Verify that Python 3 is installed by running the command `python3 –version`.
Method 2: Via Anaconda
Anaconda is a Python distribution that includes many Python packages and libraries, making it an attractive option for data science and scientific computing. To get Python 3 via Anaconda, you need to start by downloading the Anaconda installer from the official website.
Pros:
- Comes with a large number of Python packages and libraries pre-installed

3. Double-click on the downloaded file to start the installation process.
4. Follow the instructions in the installer to complete the installation.
5. Verify that Python 3 is installed by running the command `python3 –version`.
Method 3: Via Python.org
You can also get Python 3 directly from the official Python website. This method is recommended if you prefer to use a standalone installation of Python without other dependencies.
Pros:

Why Can’t I Get Python 3 on Mac?
There are several reasons why you might have trouble getting Python 3 on your Mac:
1. Xcode not installed: Xcode is a required dependency for installing Python 3 on Mac, so be sure to install it before proceeding with any of the methods above.
2. Lack of admin access: Some installation methods may require administrator access to your Mac, so be sure to check that you have the appropriate permissions.
3. Outdated software: If you have an old version of Python or Homebrew already installed, it may cause conflicts with the installation of Python 3.
To fix these issues, you can try the following fixes:
1. Install Xcode from the App Store or the Apple Developer website before proceeding.
2. Make sure that you have administrator access to your Mac account.
3. Uninstall any old versions of Python or Homebrew before installing Python 3.
Implications and Recommendations
Here are some recommendations for getting Python 3 on your Mac:
1. Always install Xcode first before attempting to install Python 3.
2. Consider your requirements and skill level before choosing an installation method.
3. If you are new to Python or want a complete data science environment, consider using Anaconda.
4. If you only need Python and prefer a standalone installation, use method 3.
5. Be sure to keep your Python installation up to date to have access to the latest features and security patches.
