Hello, I need to enhance my last week assignment with the new requirements. Can you please assist with the following assingment since I am lost? I am including the following:

1. Assignment Information
2. Last Week Assignment

Assignment Information:

Week 8 : Read / Write

 

Instructions

 

# This is the flower box and it should at the beginning of each assignment

 

# You must add comments to your  code

# Program name : Wk8_firstname_lastname.py

# Student Name :

# Course : ENTD220

# Instructor : My  instructor

# Date : Any Day

 

# Copy Wrong : This is my  work

You are going to enhance the prior assignment by doing the following

1) Add menu items to write to a file and to read from a file

2) Make a class w rfile() with two methods to write the results to a file, and to read

the results from a file.

3)Use the same output from last  assignment

Last Week Assignment:
