how to Write a TCP socket server in python code example

Example 1: 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()

Example 2: tcp server using sockets in python

import socket
from socket import *
import json

serverPort = 6100
serverSocket = socket(AF_INET, SOCK_STREAM)
# Avoiding : Python [Errno 98] Address already in use


serverSocket.bind(("", serverPort))
serverSocket.listen(1)

# TCP Server
print("The server is listening on PORT 6100")

while 1:

	connectionSocket, addr = serverSocket.accept()
	data = connectionSocket.recv(1024)

	# De-serializing data
	data_loaded = json.loads(data)
	
	print("client Sent :\n ", data_loaded)
	
	# Sending response
	connectionSocket.send(str.encode("Mil gya data"))


connectionSocket.close()
