Getting and Installing MacPython
================================

-encouraged to install the most recent version of Python from the Python website
-(http://www.python.org). A "universal binary" build of Python 2.5, which runs
-natively on the Mac's new Intel and legacy PPC CPU's, is available there.

What you get after installing is a number of things:
The Apple-provided build of Python is installed in

IDLE includes a help menu that allows you to access Python documentation. If you
are completely new to Python you should start reading the tutorial introduction
