It became official earlier today that David Beazley and myself will be co-editing/co-curating the next edition (the Third Edition) of the Python Cookbook. That’s really exciting. Here’s why:
It’s Python 3, Cover to Cover
Go big or go home. The third edition will be a Python 3 Cookbook. This by itself makes this a rather large undertaking, since it means modules used in earlier editions that don’t work in Python 3 can’t be used, and so those old recipes will need to be scrapped or rewritten.
You heard it right: if a module used in the last edition of Python Cookbook doesn’t work in Python 3, it won’t be in this edition. This includes some modules for which several recipes already exist, like dateutil and wxPython, and other modules I would’ve liked to use for illustrative purposes, like Tornado and psycopg2. I guess there’s still some time for smaller modules to port to Python 3 and be left alone in this edition, but I don’t know how realistic that is for something like wxPython.
It’s going to be ok.
I can’t find any modules (yet) in the second edition for which Python 3-compatible substitutes don’t exist, and in some cases I found myself wondering why a separate module was used at all when what needs doing isn’t a whole lot of work in pure Python anyway. I guess if the module is there and stable, why not use it, eh? Fair enough.
Actually, yes. David, myself, and YOU, where YOU is anyone who posts good Python 3 recipes to the ActiveState ‘Python Cookbook’ site. This is actually not new. If you look at the last edition, you’ll see separate credits for each recipe. The Python Cookbook has always been a community effort, featuring recipes by some very familiar names in the Python community.
Anyway, just in case that wasn’t direct enough:
Basically, ActiveState gives us free reign over their Python Cookbook content, so it’s a convenient way to let the community contribute to the work. If it’s in there, and it’s good, we can use it. They’re cool like that.
Answer these in the comments, or send email to Dave and I at PythonCookbook at oreilly.
- What are your three favorite recipes from either the 1st or 2nd edition?
- What are your three least favorite recipes from either the 1st or 2nd edition?
- What are three things (techniques, modules, basic tasks) you’d like to see covered that weren’t covered in earlier editions?
Three Cool Things About the Third Edition
- Tests. When the book comes out, we’ll make the unit tests for the recipes available in some form that is yet to be determined (but they’ll be available).
- Porting help. We’re not going to leave module authors out in the cold. We’re going to provide some help/advice. We’ve both written code in Python 3, and dealt with the issues that arise. I’m still porting one of my projects and have another in line after that, so I’ll be dealing with it even more.
- Dave and I are both overwhelmed with excitement about this book, about Python 3, and about working with you on it. Come help us out by posting Python 3 recipes (tests are also nice, but not required) on ActiveState, and shoot us an email at PythonCookbook at oreilly dotcom.
There will be other cool things, too. We’ll let you know, so stay tuned to this blog, Dave’s blog, and you should definitely follow @bkjones and @dabeaz on Twitter, since we’ll be asking for opinions/resources/thoughts on things as we go.
