Adding nothing to the discussion, let me just mention how Scheme (my
second favourite language) does it:

(if bool true-result else-result)

Well, of course this isn't relevant to Python because statements are not
expressions, but there might be something in it: if could be also used
as a function taking three arguments:

print if(long_answer, "Very good!", "correct")

I have no idea how this will play with the parser. Anyone?
