When I run that, I get:

davea at think2b:~/zzztemp$ python juan.py
   File "juan.py", line 8
     target_host = 'www.google.com'
               ^
IndentationError: expected an indented block
davea at think2b:~/zzztemp$

So you might want to fix the indentation.  And add a call to main() at 
top level.

Once I do that, I get approximately the same thing you post below.

Could it be because google.com doesn't want automated queries?  That's 
what they say in the text there.
