Write a Python class Restaurant with attributes like menu_items, book_table, and customer_orders, and methods like add_item_to_menu, book_tables, and customer_order.

Perform the following tasks now:

• Now add items to the menu.
• Make table reservations.
• Take customer orders.
• Print the menu.
• Print table reservations.

Sample Solution:

Python Code:

class Restaurant:
    def __init__(self):
        self.menu_items = {}
        self.book_table = []
        self.customer_orders = []

    def add_item_to_menu(self, item, price):
        self.menu_items[item] = price

    def book_tables(self, table_number):
        self.book_table.append(table_number)

    def customer_order(self, table_number, order):
        order_details = {'table_number': table_number, 'order': order}
        self.customer_orders.append(order_details)

    def print_menu_items(self):
        for item, price in self.menu_items.items():
            print("{}: {}".format(item, price))

    def print_table_reservations(self):
        for table in self.book_table:
            print("Table {}".format(table))

    def print_customer_orders(self):
        for order in self.customer_orders:
            print("Table {}: {}".format(order['table_number'], order['order']))

restaurant = Restaurant()

# Add items
restaurant.add_item_to_menu("Cheeseburger", 9.99)
restaurant.add_item_to_menu("Caesar Salad", 8)
restaurant.add_item_to_menu("Grilled Salmon", 19.99)
restaurant.add_item_to_menu("French Fries", 3.99)
restaurant.add_item_to_menu("Fish & Chips:", 15)
# Book table
restaurant.book_tables(1)
restaurant.book_tables(2)
restaurant.book_tables(3)
# Order items
restaurant.customer_order(1, "Cheeseburger")
restaurant.customer_order(1, "Grilled Salmon")
restaurant.customer_order(2, "Fish & Chips")
restaurant.customer_order(2, "Grilled Salmon")

print("\nPopular dishes in the restaurant along with their prices:")
restaurant.print_menu_items()
print("\nTable reserved in the Restaurant:")
restaurant.print_table_reservations()
print("\nPrint customer orders:")
restaurant.print_customer_orders()
