You may run this script from one console window and try to connect to this server from another console window by typing telnet localhost 8282.

You will see an output printed in the program window as your telnet connects to it:

Connected by 127.0.0.1:46584  

Here the host and port will defer based on the telnet instance that you are sending this request from.

After you close the server program, you can rerun it again on the same port. However, if you comment out the line that sets the SO_REUSEADDR, the server will not run for the second time.
