[Tutor] SAVING & RUNNING A PROGRAM:

[WM]

I wrote this two liner.  I wanted to save it and then to bring it back 
as  program.

IDLE 2.6      
 >>> brain = 'life'
 >>> print brain
life

I saved it as brain.py,

IDLE 2.6      
 >>> brain = 'life'
 >>> print brain
life
 >>>
python/brain.py

Traceback (most recent call last):
  File "<pyshell#2>", line 2, in <module>
    python/brain.py
NameError: name 'python' is not defined
 >>>

I think the line which drew the error message is close, but I have tried 
many versions and nothing works.
What am I doing wrong?  I get a similar result if I do the command line 
thing.l
