Installing Python 3 and IDLE

• Mac:
  1. Download Python 3.11 for Mac to your desktop, double-click on the package file, and accept the installation defaults. This will install both Python and IDLE. To start IDLE, click on Applications → Python 3.11 → IDLE.
  2. Delete the installer file from your desktop, since it is no longer needed.
  3. Optional but recommended: Open your Applications folder in Finder by clicking on the Go menu at the top of the screen and choosing Applications. Then open the Python 3.11 folder and drag the IDLE icon to your Dock. This will make it easier to start up Python by just double-clicking on the Dock icon.
• Windows:
  1. Download Python 3.11 for Windows to your desktop, double-click on the installer file, and accept the installation defaults. This will install both Python and IDLE. To start IDLE, open the Python 3.11 application from the Start menu and choose IDLE.
  2. Delete the installer file from your desktop, since it is no longer needed.
  3. Optional but recommended: Create a shortcut on your desktop to the IDLE application. This will make it easier to start up Python by just clicking on the shortcut.
• Linux:
  1. Python 3 is probably already installed. Type python3 at the command prompt to check.
  2. If you don't have it, you can get it here. Untar the archive and follow the instructions in the README file. However, there may be an easier way to install Python 3, depending on the type of Linux you're running, so ask me about it first.
