Can't run Python from cmd line

Question

I am a programming (and Python) novice. I am unable to run any python script in command prompt of my WinXP 64-bit laptop. I assigned the path and confirmed it by typing set path. I have Python32. I get the following message:

>>>python hello.py

File <”stdin”> , Line1
  Python hello.py
             ^
SyntaxError: Invalid syntax

Following is the script I tried:

#!/usr/bin/python
message = "Hello, world!"
print(message)

Answer 1

You should type this

python hello.py

at the dos/cmd prompt, not inside the Python Interpreter

Answer 2

Do it like this:

Go the directory(python32 in my example) and type python hello.py.

If you only type python in cmd then it'll launch the python interpreter after that python hello.py will return Syntax error.
