In this article, we will guide you through the whole process step by step.


1. Check if python is installed already

The very first step before rushing off to install the latest version of Python 3 on your Mac is to check if a Python version is already installed on your Mac computer. To check, type “python –version” or “python3 –version” command in the terminal. If the output shows the Python version, it means Python is installed. If not, then it’s good to go with the installation process.

2. Open the Terminal

Terminal is the default command-line interface in Mac OS X. To open it, click on the Launchpad in your Dock and look for Terminal.

3. Install Homebrew

Homebrew is an essential tool that allows you to install and manage various software packages. You can install Homebrew by pasting the following command in the terminal and pressing enter:

/bin/bash -c “$(curl -fsSL”

4. Update Homebrew

Once Homebrew is installed, update it to the latest version using the command:

brew update

5. Install Python 3

Once you have Homebrew updated, you can type in the following command to install the latest version of python 3:

brew install python

6. Verify Python Installation

After installation completes, verify that Python is properly installed. Run the following command:

python3 –version

If this command returns the version of Python installed, it shows that Python is installed correctly.

7. Install pip

Pip is a package manager for Python and it is used for installing Python packages. You can install pip by running:

sudo easy_install pip

8. Upgrade pip

Once pip is installed, you can upgrade it to the latest version using the following command:

pip install –upgrade pip

9. Install Virtualenv

Virtualenv is used to create isolated Python environments. It is essential to create virtual environments to test the code’s cross-platform functionality. Install virtualenv using the following command:

sudo pip install virtualenv

10. Create a Virtual Environment

After installing Virtualenv, create a virtual environment by entering command:

virtualenv venv

Your virtual environment is now created inside a folder called venv.

11. Activate Virtual Environment

To activate the virtual environment, type the following command:

source venv/bin/activate

The virtual environment’s name should appear in brackets in the terminal. It indicates that your virtual environment has been activated.

12. Deactivate Virtual Environment

To deactivate the virtual environment, you can enter the following command:



Well done! You have successfully installed Python 3 on your Mac. If you followed the steps outlined in this tutorial, you should have no problem installing Python on your system. Each step is crucial, especially creating a virtual environment, so we can test the code’s cross-platform functionality without altering the system’s default packages.

Tips and Tricks

1. Keep up with the updates

Keep your Homebrew updated. We recommend running the command “brew update” every time you use the terminal to ensure you have the latest version.

2. Uninstalling Python

You can uninstall Python along with all the dependencies that were installed during installation by typing in the following command:

brew uninstall python

3. Install Python versions alternatively

You can install other Python versions alternatively using the following commands.

Python 3:

brew install python

Python 2:

brew install python@2

4. Confirm installation of Homebrew, Python, and pip

You can confirm the installations of Homebrew, Python, and pip in the terminal by entering:

brew doctor

5. Create a requirements.txt File

You can create a requirements.txt file with a simple command:

pip freeze > requirements.txt

6. Create a bash alias

You can create an alias for python command by creating a bash alias. In your terminal, type the following command:

nano ~/.bash_profile

Add the following line to the bottom of the file:

alias python=’/usr/local/bin/python3’

Press Control+O to save and Control+X to exit.

7. Use IDEs

You can use an IDE to run your code. IDEs such as PyCharm, Visual Studio, and Atom are widely used among programmers. They are a great help in writing and executing your codes.

8. Clean up after installation

After the installation is complete, you can clean up all the unused dependencies that were installed along the way to save space by entering:

brew cleanup

9. Install Python libraries

Python libraries are collections of modules that are pre-written codes to perform particular functionalities. You can install Python libraries using pip. Just type in:

pip install library_name

10. Troubleshooting

If you encounter any errors or issues during the installation process, you can troubleshoot them by following the steps in the official Python documentation or look up forums online to find a solution to your problem.

Congratulations! You can now install Python 3 on your Mac computer with ease. We hope that this article was helpful in guiding you through the installation steps. Happy coding!
