Python server “Only one usage of each socket address is normally permitted”

Question

I\'m trying to create a very basic server in python that listens in on a port, creates a TCP connection when a client tries to connect, receives data, sends something back,

Answer 1

Enable the SO_REUSEADDR socket option before calling bind(). This allows the address/port to be reused immediately instead of it being stuck in the TIME_WAIT state for several minutes, waiting for late packets to arrive.

s.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
