how to create a socket in python3 code example

Example 1: python socket server

import socket

socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
socket.bind(('', 15555))

while True:
        socket.listen(5)
        client, address = socket.accept()
        print "{} connected".format( address )

        response = client.recv(255)
        if response != "":
                print response

print "Close"
client.close()
stock.close()

Example 2: python3 socket server

import socket
import os

sock_file = "/tmp/python_socket"

if os.path.exists(sock_file):
    os.remove(sock_file)

sock = socket.socket(socket.AF_UNIX, socket.SOCK_STREAM)
sock.bind(sock_file)
sock.listen()
print("Listening...")
while True:
    conn, _addr = sock.accept()
    datagram = conn.recv(1024)
    request = datagram.decode('utf-8')
    conn.send(str("Back at you:"+request).encode('utf-8'))
