What values are considered false?

Both are valid questions.

Philosophically, I would say that () and "" are different because tuples can
contain objects of any type, while strings can only contain characters.

As for why 0, None, "", [], and () are not == each other, it is because each
has a type associated with it.  Wouldn't you agree that objects of different
types are generally considered different?
