what exactly is "None" ?

[Andrei Doicin]

I know that "None" is the Boolean false value that
gets thrown out when there's nothing to return or a
function doesn't manage to reach the end of itself and thus "return
whatever", but *what* (in Python terms) exactly is equal to "None" ???

I ask this as I'm trying to set up some conditional statements that do
something if "whatever" is equal to "None".

thanks
