Nope. PEP308 to introduce a ternary operator like idiom has been 
rejected (see: 
http://www.sourcekeg.co.uk/www.python.org/peps/pep-0308.html),
but you can emulate it:

 >> bool = False
 >> s = "This is "  + ('false', 'true')[bool]
 >> print s
This is false

In this case bool evaluates to 0 and 'false' is at index 0  of the tuple 
('false', 'true').
