Connect Multiple Clients To One Server In Python Socket Code Example

Example 1: multiple clients in socket programming python

import socket

ClientSocket = socket.socket()
host = '127.0.0.1'
port = 1233

print('Waiting for connection')
try:
    ClientSocket.connect((host, port))
except socket.error as e:
    print(str(e))

Response = ClientSocket.recv(1024)
while True:
    Input = input('Say Something: ')
    ClientSocket.send(str.encode(Input))
    Response = ClientSocket.recv(1024)
    print(Response.decode('utf-8'))

ClientSocket.close()

Example 2: multiple clients in socket programming python

import socket
import os
from _thread import *

ServerSocket = socket.socket()
host = '127.0.0.1'
port = 1233
ThreadCount = 0
try:
    ServerSocket.bind((host, port))
except socket.error as e:
    print(str(e))

print('Waitiing for a Connection..')
ServerSocket.listen(5)


def threaded_client(connection):
    connection.send(str.encode('Welcome to the Server\n'))
    while True:
        data = connection.recv(2048)
        reply = 'Server Says: ' + data.decode('utf-8')
        if not data:
            break
        connection.sendall(str.encode(reply))
    connection.close()

while True:
    Client, address = ServerSocket.accept()
    print('Connected to: ' + address[0] + ':' + str(address[1]))
    start_new_thread(threaded_client, (Client, ))
    ThreadCount += 1
    print('Thread Number: ' + str(ThreadCount))
ServerSocket.close()
