How refers a method inside own parent class in Python-CodePudding

I need to force Python to call a method of the parent class completely ignoring whether or not the child classes have that method overridden.

I don't want to know if my child classes used polymorphism for that function, I just want to call the behavior of the parent class.

Example of how it would look in PHP:

<?php

class Dog {
    public function sound() {
        self::prepare();
        echo 'au au!';
    }

    public function prepare() {
        echo 'preparando parent!';
    }
}


class Boxer extends Dog {
    public function sound() {
        parent::sound();
    }

    public function prepare() {
        echo 'preparando box!';
    }
}

$boxer = new Boxer();
$boxer->sound();

The output would be:

preparando parent!
au au!

Note that I'm using SELF to tell PHP that I want the PARENT class method. If I wanted to call PREPARE from the child class, I could use $THIS and then I would have the output:

preparando box!
au au!

I wrote the following class in PYTHON:

class Dog:
    def sound(self):
        self.prepare()
        print('au au!')

    def prepare(self):
        print('preparando parent!')

class Boxer(Dog):
    def sound(self):
        super().sound()

    def prepare(self):
        print('preparando box!')

dog = Boxer();
dog.sound()

And I'm getting the following output:

preparando box!
au au!

The question is: How do I make my python class behave like PHP when I use self?

CodePudding user response：

If you want specifically to call the Dog implementation of prepare, you can use Dog.prepare(self).

class Dog:
    def sound(self):
        Dog.prepare(self)
        print('au au!')

    def prepare(self):
        print('preparando parent!')

But if you don't really want to override prepare in your subclass, maybe it would make more sense to give the methods different names.

Based on the answers from the guys and, mainly, from @sahasrara62, I managed to make some changes and arrive at a solution:

class Dog:
    nick = 'big'

    def sound(self):
        self.prepare()
    
        print(self.nick)
        print('au au!')

    def prepare(self):
        print('preparando parent!')

class Boxer(Dog):
    def __init__(self):
        self.nick = 'little'
    
    def sound(self):
        Dog.sound(self)

    def prepare(self):
        print('preparando box!')

dog = Boxer();
dog.sound()

With the following output (preserving states, inclusive):

preparando box!
little
au au!
