    Unit Test 2 - PP - WS - 2021-QP1

    Uploaded by

    Sailakshmi Reddy
    This document appears to be a test for a Python programming course assessing object-oriented concepts. It contains two questions with multiple parts assessing inheritance, abstract methods, classes and objects, exception handling, and arithmetic calculations. Students are asked to write Python code to demonstrate single inheritance with countries and states, implement abstract methods with an example, create a student result system using classes and constructor overloading, and design an arithmetic calculator handling different operations and errors. The test aims to assess students' understanding of Python programming and OOP concepts at a K2 understanding level.

    b 2 CO3 K2
    Design an arithmetic calculator with different arithmetic operations.
    Your calculator has to perform the following operations - addition,
    subtraction, multiplication, division. Display a menu of the above
    operations and let the user choose from the menu. Based on user
    choice, perform the operation and also predict what kind of error can
    occur for the operation. If the user enters any erroneous input, handle
    the error for different input formats. Demonstrate the exception
    handling.
