Pylint: Enum: Instance of 'int' has no 'value' member (no-member)

[zhongshangwu]

Steps to reproduce

#! python3

from enum import Enum

class BaseEnum(Enum):

    def some_behavior(self):
        pass

class MyEnum(BaseEnum):

    FOO = 1
    BAR = 2

print(MyEnum.FOO.value)

Run pylint on the above file.

Current behavior

E: 16, 0: Instance of 'int' has no 'value' member (no-member)

Expected behavior

No error.

(Subclassing an enumeration is allowed only if the enumeration does not define any members. )

Thank you for the report!

Notably, this affects enum.Flag and other standard classes which derive from Enum.

class Foo(enum.Flag):
    NONE = 0
    BAR = 1
    BAZ = 2

print(Foo.NONE.value)

I believe it's fixed in a recent release.
