Students: Section 11.12 is a part of 1 assignment: Wk 5: Ch. 11 zyLabs (due Mon] Requirements: zyLab Entire class due: 02/06/2020, 5:59 PM 11.12 LAB*: Program: Online shopping cart (continued) This program extends the earlier "Online shopping cart" program. (Consider first saving your earlier program). (1) Extend the Item ToPurchase class to contain a new attribute. (2 pts) • item_description (string) - Set to "none" in default constructor Implement the following method for the Item To Purchase class. • print_item_description - Prints item_description attribute for an ItemToPurchase object. Has an Item ToPurchase parameter. Ex. of print_item_description() output: Bottled Water: Deer Park, 12 oz. (2) Build the Shopping Cart class with the following data attributes and related methods. Note: Some can be method stubs (empty methods) initially, to be completed in later steps. • Parameterized constructor which takes the customer name and date as parameters (2 pts) • remove_item o Removes item from cart_items list. Has a string (an item's name) parameter. Does not return anything. If item name cannot be found output this message: Item not found in cart. Nothing removed. • modify_item o Modifies an item's description, price, and/or quantity. Has parameter ItemToPurchase. Does not return anything. o If item can be found (by name) in cart, check if parameter has default values for description, price, and quantity. If not, modify item in cart. o If item cannot be found (by name) in cart, output this message: Item not found in cart. Nothing modified. • get_num_items_in_cart0 (2 pts) o Returns quantity of all items in cart. Has no parameters. • get_cost_of_carto (2 pts) o Determines and returns the total cost of items in cart. Has no parameters. • print_totalo o Outputs total of objects in cart. o If cart is empty, output this message: SHOPPING CART IS EMPTY • print_descriptions() o Outputs each item's description. Ex. of print_total output: John Doe's Shopping Cart - February 1, 2016 Number of Items: 8 Nike Romaleos 2 @ $189 = $378 Chocolate Chips 5 @ $3 = $15 Powerbeats 2 Headphones 1 @ $128 = $128 Total: $521 Ex. of print_descriptions() output: John Doe's Shopping Cart - February 1, 2016 Item Descriptions Nike Romaleos: Volt color, Weightlifting shoes Chocolate Chips: Semi-sweet Powerbeats 2 Headphones: Bluetooth headphones Ex. of print_total output: John Doe's Shopping Cart - February 1, 2016 Number of Items: 8 Nike Romaleos 2 @ $189 = $378 Chocolate Chips 5 @ $3 = $15 Powerbeats 2 Headphones 1 @ $128 = $128 Total: $521 Ex. of print_descriptions() output: John Doe's Shopping Cart - February 1, 2016 Item Descriptions Nike Romaleos: Volt color, Weightlifting shoes Chocolate Chips: Semi-sweet Powerbeats 2 Headphones: Bluetooth headphones (3) In main section of your code, prompt the user for a customer's name and today's date. Output the name and date. Create an object of type Shopping Cart (1 pt) Ex. Enter customer's name: John Doe Enter today's date: February 1, 2016 Customer name: John Doe Today's date: February 1, 2016 (4) Implement the print_menu() function. print_menu() has a Shopping Cart parameter, and outputs a menu of options to manipulate the shopping cart. Each option is represented by a single character. Build and output the menu within the function. If the an invalid character is entered, continue to prompt for a valid choice. Hint: Implement Quit before implementing other options. Call (6) Implement Output item's description menu option. (2 pts) Ex OUTPUT ITEMS' DESCRIPTIONS John Doe's Shopping Cart - February 1, 2016 Item Descriptions Nike Romaleos: Volt color, Weightlifting shoes Chocolate Chips: Semi-sweet Powerbeats 2 Headphones: Bluetooth headphones (7) Implement Add item to cart menu option. (3 pts) ADD ITEM TO CART Enter the item name: Nike Romaleos Enter the item description: volt color, Weightlifting shoes Enter the item price: 189 Enter the item quantity: (8) Implement remove item menu option. (4 pts) REMOVE ITEM FROM CART Enter name of item to remove: Chocolate Chips (9) Implement Change item quantity menu option. Hint: Make new Item ToPurchase object before using Modifyltem() method. (5 pts) Enter name of item to remove: Chocolate Chips (9) Implement Change item quantity menu option. Hint: Make new Item To Purchase object before using Modifyltem() method. (5 pts) Ex: CHANGE ITEM QUANTITY Enter the item name: Nike Romaleos Enter the new quantity: LAPIVITY LAB ACTIVITY 11.12.1: LABUP 11.12.1: LAB*: Program: Online shopping cart (continued) 8/29 main.py Load default template...
