super-init-not-called / W0231#

Message emitted:

__init__ method from base class %r is not called

Description:

Used when an ancestor class method has an __init__ method which is not called by a derived class.

Correct code:

class Fruit:
    def __init__(self, name="fruit"):
        self.name = name
        print("Creating a {self.name}")


class Apple(Fruit):
    def __init__(self):
        super().__init__("apple")

Problematic code:

class Fruit:
    def __init__(self, name="fruit"):
        self.name = name
        print("Creating a {self.name}")


class Apple(Fruit):
    def __init__(self):  # [super-init-not-called]
        print("Creating an apple")
