This will depend on when the test is run:

a = 6
b = a
a is b # True

b = 5
a is b # False

The latter is false because the binding of "b" to the int 6 was broken
in order to bind b to the int 5.

I might also suggest you restrain from trying to correct respondents
on these matters until you yourself understand them. It's only polite.
