How to refer to the parent class in a class?

The super() function is used to refer to the parent class.

class Parent:
    def __init__(self, value):
        self.value = value

class Child(Parent):
    def __init__(self, value, extra_value):
        super().__init__(value)  # Call the parent class's __init__
        self.extra_value = extra_value

    def display(self):
        print(f"Parent value: {self.value}")
        print(f"Child extra value: {self.extra_value}")
        super().display_parent_method() # Call the parent class's method

    def display_parent_method(self):
        print("This is a method from the parent class.")
