Objectives:
To enable students to write, execute a program in Python. Moreover to familiarize students with the concepts of:• Classes and objects
• Constructor
• Object declaration
• Methods/functions callingAssignment Submission Instructions
You have to submit only.py file on the Assignments interface of CS441 at VULMS. Assignment submitted in any other format will not be accepted and will be graded zero marks.Lectures Covered: This assignment covers Weeks # 03 - 05
Deadline
Your assignment must be uploaded/submitted on or before 28/09/2019.Question statement:
Write a Python program that will create a class named Product.
This class will have 4 data members:
- Name
- Brand
- Price
- Quantity
The Product class will have the following setter functions:
setName (), which takes a single parameter
setBrand(), which takes a single parameter
setPrice(), which takes a single parameter
setQuantity(), which takes a single parameterThe Product class will have the following getter functions:
getName()
getBrand()
getPrice()
getQuantity()You are required to write a parameterized constructor for this class.
In parameterized constructor, you will initialize all the data members with the values passed to it as an arguments. The message “Parameterized constructor called” should be displayed whenever an object is created with the parameterized constructor.
Now, create an object by using the parameterized constructor and display the values of data members through calling getters functions.
Then set the values of the data members by calling the setters functions and then display its values by calling getters functions.
Sample Output:
To solve this assignment, you need to install latest Python compiler or you can run (check) your code through online compiler at the following link:
