from weakref import WeakKeyDictionary
from collections import defaultdict
from uuid import uuid4

class UniqueIdMap(WeakKeyDictionary):
    def __init__(self, dict=None):
        super().__init__(self)
        self.data = defaultdict(uuid4)
        if dict is not None:
            self.update(dict)


uniqueidmap = UniqueIdMap()


def uniqueid(obj):
    return uniqueidmap[obj].int



class A:
    def __init__(self) -> None:
        self.x = 0

a = A()

x = [a]
uniqueid(x)
print(uniqueidmap.keyrefs())
del x
print(uniqueidmap.keyrefs())

上述代码会报错
