Class Structure

• MenuItem - Represents individual menu items
• AbstractMenu - Abstract base class defining menu operations
• Menu - Implements menu management functionality
• TotalSales - Extends Menu to calculate and display sales
• RestaurantManagementSystem - Main class orchestrating the application

🎓 OOP Concepts

1. Abstraction

The AbstractMenu class uses Python's ABC module to define abstract methods that must be implemented by subclasses:

@abstractmethod
def add_item(self, data, foodname, price):
    pass

2. Inheritance

TotalSales inherits from Menu, extending functionality:

class TotalSales(Menu):
    def calculate_total_sale(self):
        # Implementation

3. Encapsulation

Private attributes are used to protect sensitive data:

self.__pass = "1234"  # Private password attribute

4. Polymorphism

Method overriding in the TotalSales class:

def display(self):
    super().display()  # Calls parent method
    # Additional functionality
