Optional static typing for Python
**Bug Report** I think I've uncovered a false positive in `mypy`'s type-checking of `is` operator with `Enum`s. See below for details. I know that `Enum`s are a bit funky, so...
Function with generic class and generic value arguments are not inferred when generic is a TypedDict
**Bug Report** When defining a function expecting a generic class and a generic value — tied to the same `TypeVar` —, mypy is not able to infer the type of...
## Objective This PR introduces a new HTML reporter (`html-direct`) that generates reports directly using Python, without relying on XSLT transformations. This solves the long-standing issue #909 regarding WebKit browsers...
**Bug Report** In the example below, mypy reveals the type to be `Any`, whereas Pyright correctly detects `Bar` Note that replacing `T | None` with `T` makes Mypy also infer...
**To Reproduce** ```python from typing import Any import numpy as np import numpy.typing as npt def plus1(array: npt.NDArray[np.integer[Any]]) -> None: array += 1 ``` **Expected Behavior** No error **Actual Behavior**...
This pull request contributes to issue #5917, which encourages the decomposition and simplification of overly long methods to improve code clarity and maintainability. ### Summary of changes Refactored the `combine_function_signatures`...
**Bug Report** mypy is raising an internal error when attempting to combine special types in a TypedDict using the alternative functional syntax. **To Reproduce** ```python from typing import NotRequired, TypedDict...
