mypy 1.17 errors on attrs dict update with keyword argument syntax

[zmoon]

Example where I noticed it:

uscrn/data.py:56: error: No overload variant of "update" of "MutableMapping" matches argument type "datetime"  [call-overload]
uscrn/data.py:56: note: Possible overload variants:
uscrn/data.py:56: note:     def update(self, SupportsKeysAndGetItem[Optional[Hashable], Any], /) -> None
uscrn/data.py:56: note:     def update(self, Iterable[tuple[Optional[Hashable], Any]], /) -> None

where that line is doing:

df.attrs.update(created=datetime_instance)

Simplified example not specific to pandas:

from typing import Any, Hashable, MutableMapping

d: MutableMapping[Hashable, Any] = {"a": 1}

d.update({"b": 2})  # fine
d.update([("c", 3)])  # fine
d.update(d=4)  # mypy error

t.py:7: error: No overload variant of "update" of "MutableMapping" matches argument type "int"  [call-overload]
t.py:7: note: Possible overload variants:
t.py:7: note:     def update(self, SupportsKeysAndGetItem[Hashable, Any], /) -> None
t.py:7: note:     def update(self, Iterable[tuple[Hashable, Any]], /) -> None

This is an issue for typeshed . See python/typeshed#12456

Closing here.

@Dr-Irv I'm not sure that issue you linked is related. mypy was fine with this until the recent 1.17 release. Should I open issue in mypy or typeshed?

I don't think you need a new issue. With pyright, I get the same error, and it is due to typeshed. If I change typeshed, the error goes away for pyright. I'm guessing the same would be true for mypy - it's that I just don't know how to change the typeshed that is embedded for mypy
