Networking in Python

 Networking in Python

Networking is a way to connect and communicate between different computers and devices. Here's an example of defining a simple client-server connection using the socket module:

python

import socket

# Server

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

s.bind(('localhost', 1234))

s.listen(1)

conn, addr = s.accept()

print('Connected by', addr)

data = conn.recv(1024)

conn.sendall(data)

conn.close()

# Client

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

s.connect(('localhost', 1234))

s.sendall(b'Hello, world')

data = s.recv(1024)

print('Received', repr(data))

s.close()

In this example, we define a simple client-server connection using the socket module. We first create a socket object and bind it to a specific address and port. We then listen for incoming connections and accept a client connection when it arrives. The server then receives some data from the client, sends it back, and closes the connection.

On the client side, we create a socket object and connect it to the server address and port. We then send some data to the server, receive a response, and close the connection.
