super-without-brackets (PLW0245)

Derived from the Pylint linter.

Fix is always available.

What it does

Detects attempts to use super without parentheses.

Why is this bad?

The super() callable can be used inside method definitions to create a proxy object that delegates attribute access to a superclass of the current class. Attempting to access attributes on super itself, however, instead of the object returned by a call to super(), will raise AttributeError.

Example

class Animal:
    @staticmethod
    def speak():
        return "This animal says something."


class Dog(Animal):
    @staticmethod
    def speak():
        original_speak = super.speak()  # ERROR: `super.speak()`
        return f"{original_speak} But as a dog, it barks!"

Use instead:

class Animal:
    @staticmethod
    def speak():
        return "This animal says something."


class Dog(Animal):
    @staticmethod
    def speak():
        original_speak = super().speak()  # Correct: `super().speak()`
        return f"{original_speak} But as a dog, it barks!"
