            Open IDLE

            You can open IDLE in three steps:

            1. Open Finder and click Applications.

            2. Double-click the Python 3.9 folder.
            3. Double-click the IDLE icon.

            IDLE opens a Python shell in a new window. The Python shell is an
            interactive environment that allows you to type in Python code and
            execute it immediately. It’s a great way to get started with Python!

               Note

               While you’re free to use a code editor other than IDLE if you
               prefer, note that some chapters, especially chapter 7, “Finding
               and Fixing Code Bugs,” do contain material specific to IDLE.



            The Python shell window looks like this:
