Python syntax error

sup /prog/

I literally just started learning Python, and I apparently am already confused. Trying to execute a basic "print 'Hello world!' from the cmd prompt (XP) is returning a syntax error.

The entirety of the script is as follows:
#! c:\Python25\
print "Hello, world!"

Trying to execute the file yields this:
>>> python script.py
  File "<stdin>", line 1
    python script.py
                ^
SyntaxError: invalid syntax

(parser is under the t in case the formatting doesn't work)

I can run the module from IDLE, but not from the command prompt. Ideas?

try
import script
