Software allowed to develop Assignment Python editor Objectives: To enable students to write, execute a program in Python. Moreover to familiarize students with the concepts of: • Variables and operators • Conditional statements • Loop structures Assignment Submission Instructions You have to submit only.py file on the Assignments interface of CS441 on VULMS. Assignment submitted in any other format will not be accepted and will be graded zero marks. Assignment Write a program in Pyton programming language, which allows the user to input an integer value for a variable named upperLimit. Based on the input value, the program should perform the following tasks: • Check whether the value entered by the user falls within the range from 1 to 100. (1 and 100 included in the given range.) • Calculate and display the sum of all numbers within the range (1 to upperLimit). • Calculate and display the average of all numbers within the range (1 to upperLimit). • Calculate and display the total number of numbers within the range (1 to upperLimit). Sample output for the wrong input: [image: Uz89tPV.png] Sample output for the wrong input: [image: 1Dw0vOn.png] Sample output for the correct input: [image: ZYZEfvz.png] Deadline: The deadline to submit your assignment solution is 01/06/2020.

Lectures Covered: This assignment covers Weeks # 03 - 05 Deadline Your assignment must be uploaded/submitted on or before 18/06/2020. Question statement: Write a Python program that will create a class named Employee. This class will have 4 data members: ID Name Address Designation The Employee class will have the following setter functions: setID(), which takes a single parameter of appropriate data type setName (), which takes a single parameter of appropriate data type setAddress(), which takes a single parameter of appropriate data type setDesignation(), which takes a single parameter of appropriate data type The Employee class will have the following getter functions: getID() getName() getAddress() getDesignation() You are required to write a default constructor for this class. In the default constructor, you will initialize all the data members with the its default values. The message “Default constructor called” should be displayed whenever an object is created with the default constructor. Now, create an object by using the default 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: [image: JFfMC4w.png] 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: https://www.onlinegdb.com/online_python_compiler =====================================Ended======================================= For any query about the assignment, contact at CS441@vu.edu.pk GOOD LUCK

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 parameter The 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.
