What is port-scanner?

This project is a simple port scanner built in Python. It lets you check whether a specific network port on a given computer or server is open and reachable. You run it from a command line by providing an IP address and a port number. The tool then attempts to connect to that port and reports back whether the connection succeeded. It is a basic, single-target checker rather than a full network mapper that scans ranges of addresses automatically. Someone learning about networking or a hobbyist exploring how systems communicate might use this to test if a particular service is available on a machine, for example, checking if port 1337 is open on a server you are curious about. It could also serve as a small educational example for someone learning Python who wants to see how network connections work in practice. The README is minimal and does not go into detail about advanced features, scanning ranges of ports, or handling multiple targets. It is presented as an open-source project inviting contributions, with a straightforward design focused on doing one thing: checking a single port on a single address.
