What we're doing here is getting an argument from the instantiation process of the child class whose first argument happens to be the one we are going to be using for setting the name attribute. The second method here implements the abstract method component underscore function. Our implementation prints the name of the child. Let's move on to the composite class that also inherits from the abstract class component. We also need another attribute to store the name of the component object. Type self dot name…
