Mypy Release Notes

Next release

Change to enum membership semantics

As per the updated typing specification for enums, enum members must be left unannotated.

class Pet(Enum):
    CAT = 1  # Member attribute
    DOG = 2  # Member attribute
    WOLF: int = 3  # New error: Enum members must be left unannotated
species: str  # Considered a non-member attribute

In particular, the specification change can result in issues in type stubs (.pyi files), since historically it was common to leave the value absent:

# In a type stub (.pyi file)
class Pet(Enum):
# Change in semantics: previously considered members, now non-member attributes
CAT: int
DOG: int
# Mypy will now issue a warning if it detects this situation in type stubs:
# > Detected enum "Pet" in a type stub with zero members.
# > There is a chance this is due to a recent change in the semantics of enum membership.
# > If so, use `member = value` to mark an enum member, instead of `member: type`

class Pet(Enum):
# As per the specification, you should now do one of the following:
DOG = 1  # Member attribute with value 1 and known type
WOLF = cast(int, ...)  # Member attribute with unknown value but known type
LION = ...  # Member attribute with unknown value and unknown type
