Pylance seemingly smarter than pyright about literal values. #6153

Closed fau-st closed 1 month ago

fau-st commented 1 month ago

Environment data

Code Snippet

from enum import Enum
from typing import Literal, TypeAlias, Union, reveal_type

class SomeEnum(Enum):
    ENUM_VALUE = "VALUE"

_ENUM_VALUE = SomeEnum.ENUM_VALUE

MyTypeAlias: TypeAlias = Union[Literal[_ENUM_VALUE], None]

class SomeClass:
    member: MyTypeAlias

reveal_type(SomeClass.member)

Repro Steps

  1. Use pylance in VSCode to check the snippet.
  2. Do the same with pyright (Playground )

Expected behavior

Both tools report the same issues.

Actual behavior

pylance doesn't report an issue but pyright does. I tried to follow USING_WITH_PYRIGHT.md but I can't seem to find what's the difference between the tools.

Revealed type is "Literal[SomeEnum.ENUM_VALUE] | None" for pylance but "Unknown | None" for pyright (plus the reportInvalidTypeForm error).

It looks like pylance is able to infer that _ENUM_VALUE is a litteral value.

This is due to the fact that pylance is using a slightly-older version of pyright. Once pylance upgrades to the latest version, you will see the same error in both places.

Your code is using a variable in a type annotation, which is explicitly forbidden by the python typing spec. There was a bug in pyright where it didn't always report this error, and I recently fixed the bug.

Here's the correct way to define this type alias:

MyTypeAlias: TypeAlias = Literal[SomeEnum.ENUM_VALUE] | None

Or using Python 3.12 syntax:

type MyTypeAlias = Literal[SomeEnum.ENUM_VALUE] | None

Thank you very much for the quick answer :+1: I'm aware this snippet uses invalid constructs, it's from a third party library and I wanted to be sure where the error was coming from. Is CHANGELOG.md the right place to know about the pyright version shipped with pylance or can it be fetched somewhere else?
