Anmol 2K18CSUN01054 Btech Cse 4B: Manav Rachna University, Faridabad

The document contains a lab assignment on object-oriented programming in Python. It includes 5 problems: 1) Create a Triangle class with methods to create and print sides of a triangle, 2) Create a class to get user input and print a string, 3) Create a Rectangle class that takes length and width and computes perimeter, 4) Create a Circle class that takes a radius and computes area and perimeter, 5) Demonstrate multiple inheritance with four classes. Solutions for each problem are provided as code snippets.

BTECH CSE 4B

MANAV RACHNA UNIVERSITY, FARIDABAD


Department of Computer Science and Technology

Course: B.Tech

Subject: Programming for Problem Solving using Python(CSW208B)

Lab 9
Learning Outcome CO1: Student will be able to implement concepts of
OOPS.
1. Write a Python program that create a class tringle and define two
methods, create_triangle() and print_sides().

2. Write a Python program to create a class with two methods inputstr()


and printstr().

3. Write a Python program to create a class Rectangle that takes the


parameter length and width. The class should also contain a method for
computing its perimeter.

4.  Write a Python program to create a class Circle that takes the
parameter radius. The class should also contain two methods for
computing its area & perimeter respectively.

5. Write a Python program to demonstrate multiple Inheritance.
