You can take a look at this. Basically, it should be something like (note that the sample handling is just an example, you will have to do something better):

import threading                                                                                                                                                      
import socket   

def print_message(socket):                                                                                                                                            
  data = socket.recv(512)                                                                                                                                             
  print(data)                                                                                                                                                         

def handle_client(clientsocket):                                                                                                                                      
  print("We have a new client")                                                                                                                                         
  thread = threading.Thread(target=print_message, args=(clientsocket,))                                                                                                 
  thread.run()
