TOPSIS implementation using Python

TOPSIS-Shivam-102303881

TOPSIS-Shivam-102303881 is a Python package that implements the TOPSIS (Technique for Order of Preference by Similarity to Ideal Solution) method for multi-criteria decision making (MCDM).

TOPSIS is a widely used decision-making technique that ranks alternatives based on their relative distance from an ideal best solution and an ideal worst solution. This package allows users to easily apply the TOPSIS method on tabular data stored in CSV files using a simple command-line interface.

The package performs proper input validation, handles common user errors, and generates a ranked output with TOPSIS scores, making it suitable for academic assignments as well as practical decision-analysis tasks.
