View source for Socket code in levels of complexity

'''Complexity 1''', very simple. Connect using "telnet localhost 9988", send a few characters and then press <enter><br>
The characters are echoed back and the connection is closed<br>
<source lang="python">
#!/usr/bin/python3

import socket
import sys

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.bind(("localhost", 9988))
s.listen(1)
 
while True:
    conn, addr = s.accept()
    data = conn.recv(1024)
    conn.sendall(data)
    conn.close()

</source>
'''Complexity 2''', we can add logging<br>
<source lang="python">
#!/usr/bin/python3 
 
import socket
import logging
import sys


s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
logging.basicConfig(format='%(levelname)s - %(asctime)s: %(message)s',datefmt='%H:%M:%S', level=logging.DEBUG)
s.bind(("localhost", 9988))
s.listen(1)
 
while True:
    conn, addr = s.accept()
    data = conn.recv(1024)
    #print(data)
    logging.info(data.decode("utf-8"))
    conn.sendall(data)
    conn.close()
