## Overview

This is a small, notebook-style Bengaluru housing-data preprocessing script. Its workflow uploads a CSV through Google Colab, uses pandas to inspect missing values, and demonstrates several filling and dropping strategies. The checked-in CSV is not clearly wired into the later `read_csv` call, which names a different uploaded filename; the excerpt also does not show saved outputs. The graph therefore keeps the data source and processing steps conservative.

Main entry points: [`data_preprocessing.py`](https://github.com/shaiknawazshareef/data-preprocessing/blob/main/data_preprocessing.py) (Preprocessing workflow)
