Answer 1

As per the docs the error OSError: [Errno 48] Address already in use occurs because the previous execution of your script has left the socket in a TIME_WAIT state, and can’t be immediately reused. This can be resolved by using the socket.SO_REUSEADDR flag.

For eg:

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
s.bind((HOST, PORT))
