🔎 Python Port Scanner

A lightweight TCP Port Scanner built in Python using the socket module.

📌 Overview

This project scans a target host for commonly used TCP ports and identifies which ports are open. It was built to understand TCP connections, socket programming, and basic network reconnaissance.
