Sorry, not the case.
Help on built-in function id in module builtins:
>>> help(id)
id(obj, /)
Return the identity of an object.
This is guaranteed to be unique among simultaneously existing objects.
(CPython uses the object's memory address.)
>>> help(id)
Help on built-in function id in module __builtin__:
id(...)
>>>> help(id)

Return the identity of an object: id(x) == id(y) if and only if x is y.
The interactive help does not say that in any version newer than the
3.4 that you tested. The function does not return an address, it
returns an identity.
