| summary | If you program in Python, and you want to write Internet applications, you need this book. |
First of all, 'Network' means 'Internet.' Everything in the book concerns protocols running over IP, which is almost anything useful these days. That said, this is a lot of ground to cover -- there's FTP, HTTP, POP3, IMAP, DNS, a veritable explosion of acronyms, and this book does a great job of hitting all the ones you're likely to need.
Foundations assumes you already know Python, but nothing about network programming. The first 100 pages covers the basics of IP, TCP, UDP, sockets and ports, server vs. daemon, clients, DNS, and more advanced topics like broadcast and IPv6. And in case you already know all that, how Python deals with them. This is the only part of the book you will probably read in order. After that you pick what you need.
Find a topic you need to know how to deal with, such as using XML-RPC, and locate the appropriate section of the book. There he'll cover the basics of the topic, show you how to use the correct Python module(s) to implement it, explain any gotchas (this is key!), and write a short but functional application or two that uses it. I'm not sure why this book isn't called 'Practical Python Network Programming.' It's eminently Practical. It won't make your heart race, but it tells you exactly what you need to get the job done.
All this information is out there to find for free, but having it all collected and summarized is worth every penny. And the real value is having the edge conditions and not-so-obvious practical details explained by someone who's obviously used this stuff in the field. Python and its excellent libraries make Internet tasks relatively easy, but it's even easier with some expert help, and the libraries assume you already know what you're trying to do. For example, if you're doing a DNS.Request() record query and using a DNS.Type.ANY, it (for good reason) returns information cached by your local servers, which may be incomplete. If you really need all the records you need to skip your local servers and issue a query to the name server for the domain. This is isn't hard; you just have to know what's going on. Or do you know which exceptions can get raised if you're using urllib to fetch web pages? It's here. Exception handling is not neglected.
So you know what you're getting, here's a laundry list of topics: IP, TCP, UDP, sockets, timeouts, network data formats, inetd/xinetd, syslog, DNS, IPv6, broadcast, binding to specific addresses, poll and select, writing a web client, SSL, parsing HTML and XHTML, XML and XML-RPC, email composition and decoding, MIME, SMTP, POP, IMAP, FTP, MySQL/PostgreSQL/zxJDBC (though you won't learn SQL), HTTP and XML-RPC servers, CGI, and mod_python. As a bonus you get some chapters on forking and threading (for writing servers) and handling asynchronous communication in general.
Just to find something to complain about churlishly, I wish Goerzen had managed to do all this and make it scintillatingly brilliant and witty from cover to cover (all 500 pages); perhaps dropping juicy bon mots of gossip from the Debian project. And while I'm at it I'd like a pony. No, seriously. If you program in Python, intend to do anything Internet related, and aren't already a Python networking god, you need Foundations of Python Network Programming. In terms of 'hours I could have saved if only I had this book sooner' it would have paid for itself many times over.

For a minute there I really did think the title "Foundations of Python Network Programming" indicated that a new Python Network was being created for television and that they were laying the foundations and discussing what the programming schedule would be.
Seriously, no joke. And by the way, a Python Network would be beat the Game Show Network [gsn.com] hands down !!!

It's like maturbating in public and not cleaning up after yourself.
Yes! whenever I masturbate in public I always wipe it up afterwards! The cashier at the supermarket really appreciated that!
