literals_parameterizations_2 error

Literal"EnumClass.MEMBER" (string) used where LiteralEnumClass.MEMBER (enum member reference) is required

A quoted string like "Color.RED" is a str literal — it is NOT the same as the enum member Color.RED. When a variable is declared as LiteralColor.RED but assigned from a parameter typed as Literal"Color.RED", the types are incompatible.

from enum import Enum
from typing import Literal

class Color(Enum):
    RED = 1

def func2(a: Literal[Color.RED]) -> None:
    x1: Literal["Color.RED"] = a  # E — string literal != enum member

How to handle it

Every rule is on by default — strict is the default, not a cage. You can dial literals_parameterizations_2 down per-file or per-path from your editor or pyproject.toml, or fix the code so it type-checks. See the Type System rules and the complete diagnostic reference.
