missing-type-kwargs (ANN003)

Derived from the flake8-annotations linter.

What it does

Checks that function **kwargs arguments have type annotations.

Why is this bad?

Type annotations are a good way to document the types of function arguments. They also help catch bugs, when used alongside a type checker, by ensuring that the types of any provided arguments match expectation.

Example

def foo(**kwargs):
    ...

Use instead:

def foo(**kwargs: int):
    ...
