unprefixed-type-param (PYI001)#

Derived from the flake8-pyi linter.

What it does#

Checks that type TypeVar, ParamSpec, and TypeVarTuple definitions in stubs are prefixed with _.

Why is this bad?#

By prefixing type parameters with _, we can avoid accidentally exposing names internal to the stub.


from typing import TypeVar

T = TypeVar("T")

Use instead:

from typing import TypeVar

_T = TypeVar("_T")
