in object-oriented programming, inheritance allows a new class (subclass/derived class) to inherit attributes and methods from an existing class (superclass/base class). sometimes, in the context of inheritance, you might need to call a method from the parent class within the subclass. in python, this can be achieved using the super() function.
let's go through a step-by-step tutorial with a code example to illustrate how to call a parent class method in python.
in this example, parentclass has an _init_ method to initialize an instance with a name and a display_info method to print information about the instance.
in this step, we create a subclass that inherits from parentclass. the _init_ method of the subclass uses super() to call the constructor of the parent class, ensuring that the name is initialized. the display_info method of the subclass uses super().display_info() to call the display_info method of the parent class before adding its own information.
now, let's create an instance of the subclass and call its display_info method. this will invoke both the display_info method of the parent class and the subclass.
when you run the code, you should see the combined output from both the parent class and the subclass. the super() function allows you to call methods from the parent class and extend their behavior in the subclass.
that's it! you've successfully learned how to call a parent class method in python using the super() function. this is a fundamental concept in object-oriented programming and can be very useful when working with class hierarchies.
