## What it is
The official companion repository of example code for the third edition of 'Foundations of Python Network Programming' (Apress), revised for Python 3. It contains per-chapter scripts covering sockets, TCP/UDP, DNS, TLS, HTTP, email protocols, SSH, FTP, and RPC.

## Use cases
- learn python network programming
- example code for tcp and udp sockets in python
- how to do TLS/SSL in python
- python email sending and IMAP examples
- study material for python networking book
- python http client and server examples
- learn DNS resolution and socket names in python

## When to choose
- you are reading the book and want its runnable example code
- you want well-designed, pedagogical Python 3 networking examples
- you need reference snippets for protocols like SMTP, IMAP, FTP, or RPC in Python

## When to avoid
- you need a production-ready networking library or framework
- you want actively developed software with a license and support
- you need modern async (asyncio) networking patterns, which the third edition predates

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: http-client, http-server, websocket, rpc, email, cryptography, caching, message-queue, developer-tools
- domain: networking, programming-languages, tutorials, developer-tools, apis
- platform: python, cross-platform
- tags: book-examples, network-programming, sockets, dns, tls, smtp, imap, ftp, ssh, python3, textbook-code
