The `id` function takes its `id` (its memory location), and throws away the object. The object is destroyed.
* When we do this twice in succession, Python allocates the same memory location to this second object as well. Since (in CPython) `id` uses the memory location as the object id, the id of the two objects is the same. * When we do this twice in succession, Python allocates the same memory location to this second object as well.

* So, the object's id is unique only for the lifetime of the object. After the object is destroyed, or before it is created, something else can have the same id. * So, the object's id is unique only for the lifetime of the object.
