Help on built-in function getrefcount in module sys:

getrefcount(...)
getrefcount(object) -> integer

Return the reference count of object. The count returned is generally
one higher than you might expect, because it includes the (temporary)
reference as an argument to getrefcount().

Are there any cases when it wouldn't?

Well, as long as the object is named "object" in sys.getrefcount's
namespace, there's at least that one reference to it...

When the temporary reference which is the argument to getrefcount is
the *only* reference, eg:

>>> sys.getrefcount (set())
1

The return value for a weakly referenced object may also be not what
you "expect":

>>> s = set()
>>> sys.getrefcount(s)
2
>>> r = weakref.ref(s)
>>> r() is s
True
>>> sys.getrefcount(r())
2
