Usually please state your OS and Python versions, what you expected to 
happen, what actually happened and the full traceback if applicable.  In 
this case I'd hazard a guess that as you're trying to print something 
that evaluates to false you're not likely to see much.  You can also 
remove the semicolons as they're simply not needed.
