Python 3 - What resources are out there and best?

Hellow everyone...

My company is considering using Python 3, now I am a DBA (Oracle, PostgreSQL, MySQL). I am not a programmer/developer, but I want to learn Python so I might be of some help, at least be informed. That being said, I am looking for the best Dead Tree HC books I can buy to add to my office library.

I currently just bought and just unwrapped yesturday:

Think Python - O'Relly book - published 8/20/2012

I was considering buying these other two books of:

Python 3 Object Oriented Programming - PACKT publishing - 7/26/2010

Violent Python: A cookbook for Hackers, Forensic Analysts, Penetration Testers, and Security Engineers - Syngress - 11/22/2012

Are there any other books I should consider? Is there much different between Python 2 and 3? Are there any Python 2 books I should consider buying as well. I am a total beginner to this language.

I know some Perl, and Bash / Korn scripting in a Linux/SUSE world. Any advice would be greatly desired.

Thank you in advance.

Some of the changes are syntactical (e.g. print() is now a function instead of a keyword. Therefore print("foo") will work on both python 2 and 3, but print "foo" only works on python 2). Some are a bit more far reaching e.g. no difference between int and long now, 1/2 now returns 0.5 instead of 0 (i.e. / does floating point division in python 3. For integer division, use // operator) Unicode support is now fixed to work sanely and quite a few standard modules have been improved. To see a list of the differences, go straight to the source:
http://docs.python.org/3.0/whatsnew/3.0.html
Personally, I haven't found it too difficult to switch from python 2 to python 3.


I learned a heck of a lot about the nuances of python from the Python Cookbook. Fun fact: my copy is autographed by 2 out of the 3 authors .

"Dive Into Python" Mark Pilgrim's Free online book, novice to pro, is updated constantly, and has been rewritten for Python3

Check appendix A for the many Py2-to-Py3 differences:

ok I bought and have in my library now:

Think Python - O'Relly book - published 8/20/2012

I have ordered these other books of:

Python 3 Object Oriented Programming - PACKT publishing - 7/26/2010

Violent Python: A cookbook for Hackers, Forensic Analysts, Penetration Testers, and Security Engineers - Syngress - 11/22/2012


Core Python Applications Programming (3rd Edition) -3/19/2012

Introduction to Python Programming and Developement GUI Applications with PyQT - 12/1/2011

So I will have these (5) books to start with and dig into Python 3 with and see what else I might need to add.

Remember to do some actual programming.

"Think Python is available online for 3.0 in pdf or tex zip format. Also check wiki.python.org (it's down right now).
