Coding Assignments ( Python Object Oriented Programming )- Problems and Solutions

NOTE : The solutions are given at the last of this article. But try to write your code before taking the help of the solutions.

Problem 1 (Rectangle)

Write a Python class named Rectangle constructed by a length and a width. The Rectangle class has the following methods.

a ) constructor method

b) area(self) - returns the area of the rectangle

c) perimeter(self) - return the circumference of the rectangle

d) special method - that compares the area of 2 rectangles

Problem 2 (Circle)

Define a class named Circle which can be constructed by a radius. The Circle class has following methods

a) constructor method

b) area(self) - returns the area of the circle

c) circumference(self) - returns the circumference of the circle

Problem 3 (Triangle)

Define a Triangle class for triangle objects that have 3 properties (sides of the triangle). Write the following methods for Triangle class

1) Constructor method

2) calculate_perimeter(self) - it returns perimeter of the triangle

3) calculate_area(self) - it returns the area of the triangle

4) check_right_trinagle(self): - it returns True if the triangle is right-angle triangle otherwise returns False.

5) Write magic methods to compare the areas of two triangles.
