๐ Topic Summary
Network communication is the process of exchanging data between computers over a network. The Python socket module provides a way to create and manage network connections, allowing your Python programs to communicate with other programs on the same computer or across the internet. Think of it like sending letters; you need an address (IP address and port) and a way to send and receive (sockets).
This worksheet will help you understand the basic concepts of using the socket module, including creating sockets, binding them to addresses, listening for connections, and sending/receiving data. Let's get started! ๐
