When I was talking about such error prone form of boolean operations, I 
didn't expect to be right so quickly :p
Steven explained the truth notion with the Something/Nothing. "0" is 
Something, 0 would be Nothing. I'm not sure it makes sens anyway. I 
mean, I could easily argue that the number 0 is something. In the end I 
wonder if I shouldn't just acknowledge the python mechanism without 
trying to find any intuitive/natural/obvious logic in it, knowing that 
sometimes the Truth lies far away from the Evidence.
