invalid-overridden-method / W0236

Message emitted:

Method %r was expected to be %r, found it instead as %r

Description:

Used when we detect that a method was overridden in a way that does not match its base class which could result in potential bugs at runtime.

Problematic code:

class Fruit:
    async def bore(self, insect):
        insect.eat(self)


class Apple(Fruit):
    def bore(self, insect):  # [invalid-overridden-method]
        insect.eat(self)

Correct code:

class Fruit:
    async def bore(self, insect):
        insect.eat(self)


class Apple(Fruit):
    async def bore(self, insect):
        insect.eat(self)
