non-unique-enums (PIE796)

Derived from the flake8-pie linter.

What it does

Checks for enums that contain duplicate values.

Enum values should be unique. Non-unique values are redundant and likely a mistake.

from enum import Enum


class Foo(Enum):
    A = 1
    B = 2
    C = 1

Use instead:

from enum import Enum


class Foo(Enum):
    A = 1
    B = 2
    C = 3
