## 1.4. Python on Mac OS 9

Mac OS 9 does not come with any version of Python, but installation is very simple, and there is only one choice.

Follow these steps to install Python on Mac OS 9:

1. Download the `MacPython23full.bin` file from http://homepages.cwi.nl/~jack/macpython/download.html.

2. If your browser does not decompress the file automatically, double-click `MacPython23full.bin` to decompress the file with Stuffit Expander.

3. Double-click the installer, `MacPython23full`.

4. Step through the installer program.

5. AFter installation is complete, close the installer and open the `/Applications` folder.

6. Open the `MacPython-OS9 2.3` folder.

7. Double-click `Python IDE` to launch Python.

The MacPython IDE should display a splash screen, and then take you to the interactive shell. If the interactive shell does not appear, select Window->Python Interactive (Cmd-0). You'll see a screen like this:
