short answer: no. longer answer: write a small C extension that casts an integer (or long integer) argument to a PyObject, increments the refcount, and returns the object. or use gc.get_objects() to get a list of all GC-aware objects, and see if your object is in there. etc. all solutions are fragile, non-portable, and/or inefficient. > This comes up because of an implementation I had in mind wherein I > would store the IDs of a notionally linked-list of objects - but without > the link - I just want to store their IDs in the desired order.
