In Python, sockets are a fundamental networking concept used for communication between computers over a network. Sockets enable programs to establish connections, send data, and receive data over various network protocols, such as TCP and UDP.

import socket

# Create a TCP socket
tcp_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

# Create a UDP socket
udp_socket = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
