Circle Calculator Extension
This repository extends the original calculator application with functionality to calculate the perimeter and area of a circle based on a given radius.
Features
• Basic arithmetic calculator (addition, subtraction, multiplication, division)
• Circle calculator that computes: (with input as radius)
Details of scripts and html files
The Circle Calculator extension consists of:
• A dedicated Circle class in circle.py module and provides two main methods:
o calculate_perimeter() - Calculates the perimeter using the formula: 2πr
o calculate_area() - Calculates the area using the formula: πr²
• HTML template for the circle.html interface
• Unit test that verify the circle calculations test using test_circle.py
