socket setup & pass server not working code example

Example 1: socket programming in python

#!/usr/bin/env python3

import socket

HOST = '127.0.0.1'  # Standard loopback interface address (localhost)
PORT = 65432        # Port to listen on (non-privileged ports are > 1023)

with socket.socket(socket.AF_INET, socket.SOCK_STREAM) as s:
    s.bind((HOST, PORT))
    s.listen()
    conn, addr = s.accept()
    with conn:
        print('Connected by', addr)
        while True:
            data = conn.recv(1024)
            if not data:
                break
            conn.sendall(data)

Example 2: tcp client using sockets in python

from socket import *
import sys
import json


serverName = ""
serverPort = 6100


clientSocket = socket(AF_INET, SOCK_STREAM)
clientSocket.connect((serverName, serverPort))

sample_data = {
	"Aparna" : 1,
	"Pooja" : 2,
	"Shreya" : 3,
	"Tanishq" : 4
}

serialized_data = json.dumps(sample_data) #data serialized

# clientSocket.send(str.encode(sample_data))
clientSocket.send(str.encode(serialized_data))

response_data = clientSocket.recv(1024)
print("Response data from server : ", response_data.decode())

clientSocket.close()
