running a python script in drpython

[john]

Haveing problems writeing a program then running it in python 2.3.5 
interpreter.  Called the program test.py used chmod to make it 
executable in linux
> #! /usr/bin/python
> print 2** 8
> print 'the bright side ' + 'of life'

 >>> python test.py
   File "<stdin>", line 1
     python test.py
               ^
SyntaxError: invalid syntax
how do you run a script you create in the python interpreter?

Thanks
John
