Question

I am a python django newbie, and was going through some open source code, What does the following source code mean:

this was inside models.py of a django application.

class Sale(models.Model):
    def __init__(self, *args, **kwargs):
        super(Sale, self).__init__(*args, **kwargs)

Please keep your language simple. I am a non computer science background and new to OOP.

Answer 1

1. Define a class Sale which is a subclass of models.Model
2. Define an initializer for Sale which takes any number of positional arguments (*args) and any keyword arguments (**kwargs)
3. That initializer will invoke the initializer of the superclass (super(Sale, self).__init__) passing along all of the positional and keyword arguments it received.

Basically it “passes through” arguments to its initializer to the parent class’s initializer .
