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.
