From the Author
Two things occurred which led us here: the 1st is a shortage of books on the market to help the intermediate Python developer. What do you do after you've learned Python? You may have read Dive into Python, Beginning Python, or Learning Python, and have written some basic tools/apps but have nowhere to turn other than dive deeply into specific topics w/books about game programming, databases, graphics/multimedia, GUIs, networking, etc.
If you want more than one skill you'd have to buy a book on every topic. This is overkill, esp. if you're only interested in expanding your skillset. In those cases you're not ready to dive that deep. You'll spend a lot, read a few chapters, then they'll collect dust (unless you're being paid or want to become an expert). This is the exact reason why I wrote "Part II" of Core Python Programming calling it "Advanced Topics". After spending a year (most of 2000) writing what I thought was the entire book, I asked myself, "Wait, I've just taught all these folks Python, but I didn't really show what they could build with it." Part II was written as a result.
Another thing that happened is that the book grew quite significantly. Originally 810 pages long, it bloomed to 1120 for the 2nd ed. With the new material for the 3rd ed., a massive tome would be difficult & expensive to publish plus would cause an unnecessary burden upon readers (unless getting an electronic edition). Thus I am pleased to announce that those chapters have been extracted to form their own book, Core Python Applications Programming!
The contents have been cleaned up and retrofitted w/Python 3 examples paired w/their 2.x friends as a hybrid to help you learn both 2.x & 3.x. You'll find that many chapters have new material including: NoSQL/non-relational databases featuring MongoDB, more Microsoft Office® examples using Outlook & PowerPoint (including the text-to-slide generator some of you have seen me use at conferences), interfacing w/Twitter, using Yahoo!Mail & Gmail to send/receive email, and even doing social media analysis w/Google+! There are also brand new chapters on Web framework development using Django, an introduction to cloud computing w/Google App Engine, and text processing w/CSV, JSON, and XML. The purpose is to provide comprehensive intros to but not go deep into any particular topic; please adjust any expectations appropriately. We hope you are as excited about the new book as we are!
The material making up "Part I" of the original book will take another couple of years to complete due to all the changes coming from Python 3 and not on the horizon at this time, so if you are a programmer completely new to Python, we still recommend the 2nd edition of Core Python Programming as the best place to go learn Python as quickly and as in-depth as possible. You'll get a great preview of Core Python Applications Programming there too! Also I look forward to meeting some of you at an upcoming conference or in one of my training courses!
