We may want > to deprecate it at some point Whenever I've taught Python (quite a bit between writing, in person, and webinars), I have been very explicit in stating that id(obj) returns some unique number for each object, and mentioned that for MANY Python objects CPython users an implementation convenience of using the memory address. Every time I've explained it I've said not to rely on that implementation detail. It's not true for small integers, for example, even in CPython.
