Invalid enum extension

Used when a class tries to extend an inherited Enum class. Doing so will raise a TypeError at runtime.

Noncompliant Code:

Copy

from enum import Enum
class Color(Enum):
    ORANGE = 1
    CHERRY = 2
class Fruit(Color):
    APPLE = 3

Compliant Code:

Copy

from enum import Enum
class Color(Enum):
    ORANGE = 1
    CHERRY = 2
class Fruit(Enum):
    ORANGE = 1
    CHERRY = 2
    APPLE = 3
