This is a blank Python interpreter window. When you click on the icon to open the program, the shell is the first thing that you see: The shell is the default mode of operation for Python IDLE. If you’re just beginning your Python programming journey, then Python IDLE is a great alternative! How to Use the Python IDLE Shell Professional IDEs are more robust pieces of software and they have a steep learning curve. ![]() Python IDLE also provides several useful features that you’ll see in professional IDEs, like basic syntax highlighting, code completion, and auto-indentation.

You can simplify your workflow with Python IDLE, which will immediately start a Python shell when you open it. You can access it through the terminal or command line app on your machine. The Python shell is an excellent place to experiment with small code snippets. Then, it loops back to read the next statement. It reads a Python statement, evaluates the result of that statement, and then prints the result on the screen. The shell is a basic Read-Eval-Print Loop (REPL). Please carefully read the Important Information displayed during installation for information about SSL/TLS certificate validation and the Install best place to experiment with Python code is in the interactive interpreter, otherwise known as a shell. Both installer variants include private copies of OpenSSL 1.1.0.Consider using the new 10.9 64-bit-only installer variant, unless you are building Python applications that also need to work on older macOS systems. Both variants now come with batteries-included versions oF Tcl/Tk 8.6 for users of IDLE and other tkinter-based GUI applications third-party and system versions of Tcl/Tk are no longer used. We also continue to provide a 64-bit/32-bit variant that works on all versions of macOS from 10.6 (Snow Leopard) on. The default variant is 64-bit-only and works on macOS 10.9 (Mavericks) and later systems. For 3.7.0, we provide two binary installer options for download.Please see What’s New In Python 3.7 for more information.
