Question

Python 3 IDE/AWS

Problem

You are tasked with writing a new program for your company that keeps track of the customer’s information and his or her current bill. The company wants the name, address, phone number, and balance to be stored for each customer.

This program will demonstrate the following:

• How to use a class to organize data
• How to use methods to access the data of a class
• How to create objects from a class

Solving the Problem

Step 1

The first step in designing a class to organize data is to determine what data you want to store in the class and what methods you want to use to modify the data. You have been given the required data items, but what methods do you want to include? It is common to create accessor methods for each data item in the class.

Step 2

The next step is to create the accessor methods of the class. These methods can be used to simply set the values of the data items or even mold how the data look. In the phone number’s accessor method, a specific layout of the number is required to be set, and the balance accessor does not allow a negative balance to be entered.

Step 3

The next step is to create a list of customers in the program. A loop is used to add 5 customers. If bad input is entered into the phone or balance, then the program will continue to ask for those data.

Step 4

You can now write code to find the customer information for all of the customers or individual customers in the list.

Documentation Guidelines:

Use good programming style (e.g., indentation for readability) and document each of your program parts with the following items (the items shown between the '<' and '>' angle brackets are only placeholders. You should replace the placeholders and the comments between them with your specific information). Your cover sheet should have some of the same information, but what follows should be at the top of each program's sheet of source code. Some lines of code should have an explanation of what is to be accomplished, this will allow someone supporting your code years later to comprehend your purpose. Be brief and to the point. Start your design by writing comment lines of pseudocode. Once that is complete, begin adding executable lines. Finally run and test your program.

Deliverable(s):

Your deliverable should be a Word document with screenshots showing the source code and running results, and discuss the issues that you had for this project related to AWS and/or Python IDE and how you solved them for all of the programs listed above as well as the inputs and outputs from running them. Submit a cover sheet with the hardcopy of your work.
