Python [Errno 98] Address already in use

Question

In my Python socket program, I sometimes need to interrupt it with Ctrl-C. When I do this, it does close the connection using socket.close().

Answer 1

because you trying to run service in same port that is already running.

some time its happen because your service is not stopped in process stack. you have to kill them

no need to install anything here is the one line command to kill all running python processes.

for Linux based OS:

Bash:

kill -9 $(ps -A | grep python | awk '{print $1}')

Fish:

kill -9 (ps -A | grep python | awk '{print $1}')
