Wow, this must be at least the 4th post of the same question.
It now occurs to me that a newer Python won't help you.

Are you running this at a command prompt?
Or are you running this in some IDE?

The reason I ask this question is that at a command prompt, the above would 
probably work.

In short, please provide more context. What OS? What version of Python? What 
environment (command prompt, IDE (which one?), a standalone script, etc)?

CHeers,
