TOPSIS implementation using Python

TOPSIS-Yash-102303701

TOPSIS-Yash-102303701 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 widely used in decision analysis to rank alternatives based on their distance from an ideal best solution and an ideal worst solution. This package allows users to apply TOPSIS easily on tabular data stored in CSV files through a simple command-line interface.

The package validates inputs, handles common user errors, and generates a ranked output with TOPSIS scores, making it suitable for academic assignments as well as real-world decision analysis problems.
