Explanation:
The programming language used is python 3.
There are three parts to this code, the supper class, the child class and the main class.
The Supper Class (Dinner_combo):
The supper class is defined and it contains its three protected instances, two methods are created to select the main dish and the soup, and a third to display the customer order, the displayOrder function calls the other functions within itself and sums up the amount and prints the order list and the result.
The sub-class (Deluxe_dinner_combo):
This class inherits all the protected instances and the methods from its parent class and has another extra appetizer instance and choose_appetizer method.
the displayOrder in this subclass overrides the one in the parent class, it also includes the appetizer to its order list.
Main Module:
The user is prompted to select a dinner plan and depending on the dinner plan selected, a customer object is created and the necessary meals are called from within their methods and displayOrder method returns the items ordered, their price and the total amount.
I have attached a picture for you to see how it works.
