Unexpected keyword argument error. And yet I am unable to reproduce it outside of a big project. I have a hierarchy of dataclassed and if it is all in a single file - mypy agrees and yet once its get distributed across several packages, error emerges.
Hi! In one of my projects, there's a specific dataclass I reuse a lot that's semantically an ordered an frozen dataclass,
ediclass = partial(dataclass, order=True, frozen=True). I noticed this completely prevents mypy from treating it as a dataclass, which is 99% of mypy errors in this project.
@Hellzed Have you found a solution? From the dataclass_makers constant you provided, I found its usage https://github.com/python/mypy/blob/ec76ccafa757c6d8fbb2c83195170bf75e0ff324/mypy/plugins/default.py#L92, which is get_class_decorator_hook(). IMO chances are a custom plugin providing get_class_decorator_hook() would work.
good day
django.core.exceptions.ImproperlyConfigured: django-configurations settings importer wasn't correctly installed. Please use one of the starter functions to install it as mentioned in the docs: https://django-configurations.readthedocs.io/
that's what happens when I'm running "mypy"
[mypy]
files=wwau,../../shared
ignore_missing_imports=true
plugins =
mypy_django_plugin.main
how do I even debug this? the app runs fine
I'm having a weird behavior with dict's get method:
from typing import Dict, Generic, Optional, TypeVar
K = TypeVar("K")
X = TypeVar("X")
# def weird(k: K) -> Optional[X]:
# d: Dict[K, X]
# return d.get(k, None)
class NS_gen(Generic[K, X]):
def __init__(self, ns: Dict[K, X]) -> None:
self._dict: Dict[K, X] = ns
def get0(self, key: K) -> Optional[X]:
return self._dict.get(key, None)As is, mypy throws the error: error: Argument 1 to "get" of "Mapping" has incompatible type "K" ; expected "Optional[X]"
But if the function weird is uncommented, mypy's error disappears... I've tried to find something related to this error in github's issues, but I wasn't able to find something that looks related.
CONTRIBUTING.md talks about using pre-commit, but not on how to set it up: virtualenv -p /usr/bin/python3 .venv && .venv/bin/activate. Still it fails for me when it runs flake8 because of E704 Multiple statements on one line. Creating a tox.ini with [flake8] ignore = E704 fixed it for me. Did I miss something and/or why isn't this conf included somewhere in tox.ini, setup.cfg, pre-commit or wherever?
hello guys,
can someone tell if it is possible (in plugin) to create Expr ouf of Type, Something like we have builtins.int and want to create IntExpr?
or maybe using different words and a little of context: how can I transform OpExpr into what this operation actually produces.
something like: OpExpr [ 10 ^^ 2]? We have a pow that will create an IntExpr, right?
how can I do something like that?
Ref: kornicameister/loguru-mypy#49
This might give a little bit more context.
class BaseClass:
_class_defined_by_derived_class: ClassVar[Type[ThatClassBaseType]]
def get_new_instance(self):
return self._class_defined_by_derived_class()
class DerivedClass:
_class_defined_by_derived_class = ASubclassOfThatClassget_new_instance so that when I call DerivedClass().get_new_instance() it's correctly typed? setting aside the question of whether this class hierarchy makes sense.

Hi everyone!
I'm attempting to make a class that can house a series of decorators that can be imported from other packages. I'm running into an issue though, where I can't seem to get mypy to recognize the imported decorators
class _TaskDecorator:
def __init__(self):
self.store = {"python": python_task, "virtualenv": _virtualenv_task}
decorator = ProvidersManager().taskflow_decorators
for decorator_name, decorator_class in decorator.items():
self.store[decorator_name] = decorator_class
def __getattr__(self, name):
if self.store.get(name, None):
return self.store[name]
raise AirflowException("Decorator %s not found", name)
task = _TaskDecorator()These added functions will work at runtime, but I can't get text completion or hinting to work in my IDE.
I have attempted to create a stub file, which KIND OF works, but requires that I know the exact arguments to the methods beforehand (which is a problem as the packages can update without the main package updating). Is there anything I can do to make these @task.____ decorators show up in code completion?
