Shape Area Calculation System: Python Programming Assignment

This Python assignment focuses on developing a shape area calculation system. The program utilizes Python to calculate the areas of various geometric shapes including triangles, rectangles, circles, trapezoids, ellipses, and parallelograms. The solution includes test data and expected outputs to validate the functionality of the implemented methods. The code incorporates user input validation to handle incorrect inputs such as zero values for parameters. The program also uses functions to calculate the area for each shape and formats the output to two decimal places. The assignment demonstrates the use of conditional statements (if/elif/else), input/output operations, and mathematical functions to solve the problem. The program is designed to provide a user-friendly interface, prompting the user to select a shape and input the necessary dimensions. The program also includes error handling for invalid menu selections and parameter inputs. The code is well-documented, explaining the purpose of each code block.
