Not sure where to put example code, but here it goes: import weakref class MyObj(object): def __init__(self): self.ref = weakref.ref(self) def __del__(self): print "HERE123", self.ref() o = MyObj() o = None | |||

The behavior is documented in the C code. I don't know how it is described in the docs. Objects/typeobject.c around line 820 says: /* If we added a weaklist, we clear it. Do this *before* calling the finalizer (__del__), clearing slots, or clearing the instance dict. */ | |||

Georg, can you update the docs? Weak references *to* an object are cleared before the object's __del__ is called, to ensure that the weak reference callback (if any) finds the object healthy. | |||
