need it in python fast

The last question is a programming problem. You have been hired by small retail shop to create a program to help manage the store's sales receipts. The retail shop already has a basic object-oriented design for the software program that they need as captured in the class diagrams below. Your job is to help them write the Python code needed to realize their design. The following class diagrams will be needed to complete Parts A and B of this problem. The instructions for those parts can be found below. Part A. Write Python code that defines the two classes outlined in the class diagrams: SalesReceipt and Lineltem. ( 32 of 56 points) The solution for this part of the problem should consist of two class definitions: one for SalesRecept, and one for Lineltem. No other code is required for this part of the problem. HINTS: 1. Be sure to include__init_. methods for each class! 2. You do NOT need to implement getter/setter methods. Except for the always-required _ init. you only need to define the methods that are specified in the class diagrams. 3. Be sure to show partial work, even if you get stuck on part of the problem. 4. Assume necessary argument(s) are provided for the class attribute(s), when a new instance is created. Part B. Using the classes defined in Part A, write the Python code required to create objects that represent the data in the sales receipt below ( 24 of 56 points). In addition, print the grand total of the sales receipt. Your code should use the class definitions you created in Part A. Sales Receipt
