Need python help running code and others. Functions are ideal for use in menu-driven programs. When the user selects an item from a menu, the program can call the appropriate function. Write a menu-driven program for Burgers. Display the food menu to a user (Just show the 5 options' names and prices - No need to show the details!) Use numbers for the options and the number "6" to exit. If the user enters "6", your code should not ask any other questions, just show a message like "Thank you, hope to see you again!" Ask the user what he/she wants and how many of them. (Check the user inputs) Keep asking the user until he/she chooses the exit option. Use a data structure to save the quantities of the orders. You should use ArrayLists/Array Bags, or LinkedLists/LinkedBags (one or more of them) to save data. Calculate the price. Ask the user whether he/she is a student or a staff. There is no tax for students and a 9% tax for staff. Add the tax price to the total price. Display(print) the bill to the user. The bill includes: The food items The quantities The cost of them The total before tax Tax Total price after tax My python code: class ArrayBag(object): """An array-based bag implementation.""" # Class variable DEFAULT_CAPACITY = 10 # Constructor def __init__(self, sourceCollection = None): """Sets the initial state of self, which includes the contents of sourceCollection, if it's present.""" self.items = Array(ArrayBag.DEFAULT_CAPACITY) self.size = 0 if sourceCollection: for item in sourceCollection: self.add(item) # Accessor methods def isEmpty(self): """Returns True if len(self) == 0, or False otherwise.""" return len(self) == 0 def __len__(self): """Returns the number of items in self.""" return self.size def __str__(self): """Returns the string representation of self.""" return "{" + ", ".join(map(str, self)) + "}" def __iter__(self): """Supports iteration over a view of self.""" cursor = 0 while cursor < len(self): yield self.items[cursor] cursor += 1 # Mutator methods def clear(self): """Makes self become empty.""" self.size = 0 self.items = Array(ArrayBag.DEFAULT_CAPACITY) def add(self, item): """Adds item to self.""" if self.size == len(self): self._expand() self.items[self.size] = item self.size += 1 def _expand(self): """Doubles the capacity of self.""" old = self.items self.items = Array(2 * len(old)) for count in range(len(old)): self.items[count] = old[count] # order.py from array import ArrayBag class Order: def __init__(self): self._price_before_tax = 0 self._price_after_tax = 0 self._tax = 0 self._order_items = Array(10) def display_menu(self): print("\n----------- Food Court -----------") print("1.
