arguments-renamed / W0237

Message emitted:

%s %s %r method

Description:

Used when a method parameter has a different name than in the implemented interface or in an overridden method.

Problematic code:

class Fruit:
    def brew(self, ingredient_name: str):
        print(f"Brewing a {type(self)} with {ingredient_name}")


class Apple(Fruit): ...


class Orange(Fruit):
    def brew(self, flavor: str):  # [arguments-renamed]
        print(f"Brewing an orange with {flavor}")


for fruit, ingredient_name in [[Orange(), "thyme"], [Apple(), "cinnamon"]]:
    fruit.brew(ingredient_name=ingredient_name)

Correct code:

class Fruit:
    def brew(self, ingredient_name: str):
        print(f"Brewing a {type(self)} with {ingredient_name}")


class Apple(Fruit): ...


class Orange(Fruit):
    def brew(self, ingredient_name: str):
        print(f"Brewing an orange with {ingredient_name}")


for fruit, ingredient_name in [[Orange(), "thyme"], [Apple(), "cinnamon"]]:
    fruit.brew(ingredient_name=ingredient_name)
