IDLE
The Integrated Development Learning Environment (IDLE) is a cross-platform IDE that offers a minimal code editing experience. It has been included with Python since version 1.5.2b1.
Installing On Windows
While some Windows machines may already have Python installed, many do not. The latest version of Python 3 can be downloaded here.
Installing On macOS
Since Python 2 was sunset back in 2020, newer versions of macOS are looking to only include Python 3 pre-installed. However, it can still be downloaded here. IDLE will become available after downloading and can be accessed in the Python 3.x
folder in the “Applications” section of the Finder.
