Please correct me if I am wrong, but according to this b[2] and b[0]
are the same object. Now,
b[0] is b[2]
False
This is a true statement:
If X is Y, then id(X) == id(Y).
However, this is generally not a true statement:
If X is Y, then id(X) is id(Y).
If X and Y exist at the *same time*, then (X is Y) == (id(X) is id(Y)).
Since X and Y in the example above do not exist at the same time, it
is nonsensical to compare them.
