从dict继承时，mypy型统一
我希望以下代码可以打字，但事实并非如此。
from typing import Iterator, Type
class Parent(dict):
pass
class A(Parent):
pass
class B(Parent):
pass
x: Iterator[Type[Parent]] = (A, B).__iter__()
# error: Incompatible types in assignment (expression has type "Iterator[ABCMeta]", variable has type "Iterator[Type[Parent]]"
如果我将父班更改为，
class Parent():
pass
则可以正常工作。
有没有更好的方法让我让Mypy看到X作为类型iterator [type [parent]]时parent> parent> parent>从dict？
I would expect the following code to typecheck, but it does not.
from typing import Iterator, Type
class Parent(dict):
pass
class A(Parent):
pass
class B(Parent):
pass
x: Iterator[Type[Parent]] = (A, B).__iter__()
# error: Incompatible types in assignment (expression has type "Iterator[ABCMeta]", variable has type "Iterator[Type[Parent]]"
If I change the parent class to
class Parent():
pass
It works just fine.
Is there a better way for me to get mypy to see x as a value of type Iterator[Type[Parent]] when Parent inherits from dict?

我猜在两行的工作中做这
件事有点过度捕食
doing it on two lines works
I guess mypy's a little overeager somewhere
