The simplest way to launch a Python app or script on a Mac is to double-click the script. This starts the Python Launcher, which will launch the app for you.

This works well when using simple scripts, but I’ve found that when using more complex applications (e.g., those that use Tkinter GUIs), the app becomes sluggish and the layout changes.

I am going to describe three other methods, but before we start, it would be a good idea to check the Python version you have installed on your Mac:

Open the Terminal by pressing ⌘ + Space, typing ‘Terminal’ and pressing Return, or going to ‘Applications > Utilities > Terminal’.

Enter the following:

python3 --version

If you see something like:

Python 3.14.0

You’re ready to continue.

If not, install Python from python.org/downloads

I will also provide a download link to my ‘Jargon - Business Jargon Generator’ app that you can use to practice and learn about launching Python programs.
