how to create a socket in python 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: 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 3: 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 4: client server python socket

#!/usr/bin/python           # This is server.py file

import socket               # Import socket module

s = socket.socket()         # Create a socket object
host = socket.gethostname() # Get local machine name
port = 12345                # Reserve a port for your service.
s.bind((host, port))        # Bind to the port

s.listen(5)                 # Now wait for client connection.
while True:
   c, addr = s.accept()     # Establish connection with client.
   print 'Got connection from', addr
   c.send('Thank you for connecting')
   c.close()                # Close the connection

Example 5: python socket

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 6: 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()
