Just type "python script.py" at the OS prompt

Or in *nix you can just type script.py if you havbe a shebang 
line at the top.

You can't run it as such but you can import it.
If the script has no 

if __name__ == '__main__':
    main()

stanza then it will run as if you had executed it, if it has 
the stanza then you need to call the main funbction manually:

>>> import myscript
>>> myscript.main()
