Simply putting, Python memory manager counts references to the existing variables and if reference count is equal to zero, garbage collector automatically de-allocates the space for that variable.

Order is undefined as python has a garbage collector. To trace the order you may add a __del__ method which is known as a destructor method in Python. It is called when there are no references to the object and object is garbage collected.

See What is the __del__ method, How to call it?
