[Tutor] Running Existing Python

[Justin Bonnell]

I downloaded Python 2.7.1. I think this is a pretty basic question.
When I try to run the existing python files on the computer (hello.py), I receive a syntax error. 

Python 2.7.1 (r271:86882M, Nov 30 2010, 10:35:34) 
[GCC 4.2.1 (Apple Inc. build 5664)] on darwin
Type "copyright", "credits" or "license()" for more information.
>>> python hello.py
SyntaxError: invalid syntax

I am running Mac OS X version 10.6.6.
Shouldn't I be able to run hello.py from the IDLE interpreter?
