How do you work with sockets and network programming in Python?

Working with sockets and network programming in Python involves using the socket module, which provides low-level network communication capabilities. You can create client and server applications, exchange data over various network protocols (like TCP and UDP), and perform tasks like sending and receiving data over a network connection.

Here's a basic overview of working with sockets in Python:

import socket
#Create a socket object:
server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
#Bind the socket to an IP address and port:
server_address = ('127.0.0.1', 12345) # Example IP and port

server_socket.bind(server_address)
#Listen for incoming connections:
server_socket.listen(5)
# Accept incoming connections:
client_socket, client_address = server_socket.accept()
