Python Practice Book
- cursivedgreat 12y agoGreat piece of work and truly interactive learning. Its gonna fun to learn python.
- cstuder 12y agoFYI: It's Python 2, teaching Python 2 syntax. Given the state of the whole 2 vs. 3 debate, I'm always surprised that libaries and books don't post their requirements or used versions more prominently.
- yeukhon 12y agoMost of the writing are Python 2 and 3 compatible (sure the print statement is enough to throw Python 3 off) and this was written back in 2012 when Python 2 was still the center of the community. Maybe the author thinks writing down the interpreter (Python 2.7.1) on the first chapter is good enough. Also, this was prepared for a training if you read the side. So students who took the author's training probably knew it was for Python 2. Although I do spot a couple really "non-standard" practice, for example, the classes still using the old Python 2 syntax: class Name: vs class Name(object):
- zeckalpha 12y agoActually, leaving out `object` is the preferred convention for Python 3, as they are semantically equivalent. In Python 2, they mean different things, and you generally want to mean `class Name(object):`. Explicit is better than implicit.
- kbyers 12y agoWhy is this a 'preferred convention' for Python3? Doing this causes a lot of confusion for Python beginners that write code in Python2 (i.e. it causes them to accidentally use old-style classes). A better practice is to add the extra word i.e. 'class ClassName(object):' for both Python2 and Python3 code. This is especially true if you are writing Python tutorials. Since we are going through this Python2 to Python3 transition it is better to minimize the differences in the cases where they don't really matter (i.e. add the extra 'object' word).
- meowface 12y agoIt's considered a wart that old style classes even exist in the first place. Classes look way nicer without it. Imagine having to write `extends Object` for every Java class you make.
- kushaldas 12y agoIf you have Python 2.7.5, then print('hello') just works for you.
- anandology 12y agoThanks for the suggestion. Added a note on the index page.

- nness 12y agoHmm, noticed a few mistakes in the Getting Started section, both code, grammar and spelling. Where can we submit issues?
- echohack 12y ago...and I'm surprised there's a whole section on using recursion in Python, considering Python guards against recursion depth. (tail recursion is especially applicable here). The author seems to have a solid understanding of Python, so I'm a little confused. In general, if you use recursion in python, you're gonna have a bad time. Better to use an iterator (which is usually more memory efficient anyway because you're not slurping up the whole thing...). Of course, you can always hack it and sys.setrecursionlimit, but WHY WOULD YOU DO THIS. https://docs.python.org/2/library/sys.html#sys.setrecursionlimit https://docs.python.org/2/library/sys.html#sys.setrecursionl...

- tyng 12y agoEver since completing the Codeacademy Python course, I've been looking for simple but practical python projects that can help me learn to apply my skills. But so far the projects I found have been either too difficult or too simple (textbook like). I wonder if there is a more structured project-based learning material out there? Any suggestions?
- simonveal 12y agoIt's not specifically for python, but I have found the exercises at http://programmingpraxis.com http://programmingpraxis.com to be really good for this kind of thing (and the comments will usually contain some solutions in python).
- tyng 12y agoThis still seems more mathematical/text-book like than practical examples, reminds me of https://projecteuler.net/ https://projecteuler.net/ which is fun to do. Thanks for sharing!
- compedit 12y agoThis sounds exactly like what you're looking for! [0] You’re a new coder. You’re interested in learning how to code, not just syntax. You’re sick of monkey-see, monkey-do types of tutorials. Let’s set your teeth into some real coding. Your hand will be held in the beginning, but as you progress you’ll see yourself approaching the projects more comfortably. [0] - http://newcoder.io/ http://newcoder.io/
- tyng 12y agoThis looks cool! Will give it a go over the weekend. Thanks for sharing!
- Walkman 12y agoYou should really pick something you care about and solve a problem in that area. You will be more motivated, you will learn faster and you choose the complexity!
- erikb 12y agoJust looking through the Contents it seems like a more elaborate Tutorial? At least for me the title suggested that this book is for people who are already intermediate/advanced Pythonistas who want to improve their skills. Would be great to find a book like that.
- mobman 12y agomade by "sphinx"....another python masterpiece !!
- porter 12y agoThis is awesome. I wish this was extended to teach more advanced topics such as how to create reusable packages, big O notation, etc.
