TCP Server

import socket

   IP = '0.0.0.0'
   PORT = 9998
   def main():
       server = socket.socket(socket.AF_INET,
socket.SOCK_STREAM) server.bind((IP, PORT)) server.listen(5)   
print(f'[*] Listening on {IP}:{PORT}')
      while True:
client, address = server.accept()
          print(f'[*] Accepted connection from {address[0]}:
  {address[1]}')
          client_handler =
  threading.Thread(target=handle_client, args=(client,))
client_handler.start()
def handle_client(client_socket): with client_socket as sock:
          request = sock.recv(1024)
          print(f'[*] Received: {request.decode("utf-8")}')

      main()

To start off, we pass in the IP address and port we want the server to listen on 1. Next, we tell the server to start listening 2, with a maximum backlog of connections set to 5. We then put the server into its main loop, where it waits for an incoming connection. When a client connects 3, we receive the client socket in the client variable and the remote connection details in the address variable. We then create a new thread object that points to our handle_client function, and we pass it the client socket object as an argument. We then start the thread to handle the client connection 4, at which point the main server loop is ready to handle another incoming connection. The handle_client function 5 performs the recv() and then sends a simple message back to the client.
