I was looking at a book on python network programming and i wanted to know what would be the benefits to learning python network programming comprehensively? This would be in the context of being able to develop some really cool, ground breaking web apps. I am a python newbe so all opinions woul be appreciated.
Kind Regards

This was 4yrs ago, its crazy how much I've grown as a developer. Regarding how it has helped,  I've developed an email application, a chat application using Objective C, python Twisted on the server side, it also helped with developing my apns push notification pipeline.
The network is and always will be the sexiest arena for a hacker. An attacker can do almost anything with simple network access, such as scan for hosts, inject packets, sniff data, remotely exploit hosts, and much more. But if you are an attacker who has worked your way into the deepest depths of an enterprise target, you may find yourself in a bit of a conundrum: you have no tools to execute network attacks. No netcat. No Wireshark. No compiler and no means to install one. However, you might be surprised to find that in many cases, you’ll find a Python install.
Hence, the one benefit of python network programming I see is that one has a chance of becoming a penetration tester or an Offensive security guy.

I have no knowledge of what I was thinking when I was writing this answer. It's clearly not helpful. 
Regarding the question, making web apps is not equivalent to network programming. In network programming with python, you can start with lower level of the OSI model by using libraries like scapy. Here you can make raw packets and understand the various protocols with it. And then maybe move to application level with libraries like Scrapy which involves web scraping, making http requests, etc. But develping python web apps would use tools like flask, django, jinja, etc and the development of a web app can take the form totally different than that of a regular scripting tool.
