These scenarios will raise error "[Errno 98] Address already in use" when you create a socket at certain port:
The port was't closed. When you created a socket, but forgot to close it, or annother program hold that.
You have close the socket(or kill the process), but the port stay at TIME_WAIT status in 2 MSL(about 2 minutes).
Try "netstat" command to view port usage
such as
netstat -na
or
netstat -na |grep 54321

Stop the program or the service which is the port which you are trying to use. Alternatively, for whatever program which you are trying to write, use a PORT number which is a sufficiently high number (> 1024 for sure) and is unused.

lets say i am using 54321 port. how can i stop it? sock.close('54321') ?

If your program does not own that application running at the port, you cannot stop it. And sock.close() will shutdown the program. No need of giving port. Looks like a little reading of "Socket Programming Howto" would be helpful to you.
