This download includes a PDF, paid HTML view you can access from There is a new version of this book called Learn Python 3 The Hard Way which you can. Learn Python The Hard Way Release Zed A. Shaw June 24, CONTENTS The Hard Way Is Easier 3 Reading and Writing. Welcome to the 2nd Edition of Learn Python the hard way. You can visit the companion site to the book at tvnovellas.info
I love the idea of the book being online in HTML for free, but you can pay for a better learning experience: It reminds me of the same thing, and I think it's a great trend. Maybe he doesn't realize how much people are willing to pay? I bet he's leaving a lot of money on the table with his current pricing scheme. Maybe it's not just about the money? It isn't for me, either. Indeed, I've never received a single complaint about the price of any Rails Tutorial product.
What's that about 30?
LPTHW starts to get more complicated around exercise It's a good, well-informed, easy read. Don't let that stop you from trying the book. These days we're a RoR shop, but I needed to pick up Python rather quickly for a side project. LPTHW is structured well for beginners, but it just so happens it's structured well for pros too.
The exercises are a great way to discover portions of Python that aren't intuitive to you. You'll hit roadblocks where your code won't run. That's when you'll really learn.
I would still recommend it, even to those who know how to program. A lot of the book is just non-stop typing as fast as you can. The benefit to me was how it improved my 'muscle memory' when actually sitting down to write something on my own.
There was less stumbling over little things like -- "how do import a library again? For example, I wrote unit tests in one of the 'extra credit' assignments to explain a bunch of python's symbols.
Zed, are you going to be writing any other books for Python, like Python 3 or more advanced topics? Maybe "Advanced Python the Hard Way? Nope, I'm not writing any more Python books, instead I'm writing a book on C. If you're open to suggestions, I and I'm sure lots of others would love to see one for objective C. Does anyone know of any good books for people that are proficient with Python and want to learn more about the language and come closer to being an expert?
Also, it's kind of a bummer that there's no. With no sarcasm intended, carefully read over the Python manual, sentence by sentence, every so often. You'll learn something each time for quite a few iterations. Things that seemed a mass of pointless double-underscores will start to make sense. Plus, you can't understand the solution until you encounter the problem.
Reading the language manual every so often after you've encountered more problems is often enlightening. I've been working through the bash man page this way for years.
It's taking me a while because I don't really do much shell scripting, so I don't encounter very many problems that I need solutions to. I guess I would recommend Mark Lutz books, but really, if you are already proficient in Python then I'd say go out and read code and implement algorithms in Python to learn more.
As for. It's supposed to be coming out on the Kindle store soon, but all of my previews of it just look like junk. I got it as close as I could, but. If you've got a suggestion on making code look nice in. Perhaps the same solution could work with code in.
Apparently that's what BigNerdRanch does. Seriously, that just makes my inner nerd cry. Has the book "Learn C the hard way" released yet? I've laid a stake in the ground for it, and will start writing it for sure in a couple of weeks. I sort of need a break after this. There's an open Git repo for it, but so far it's quiet.
Stick the repo's RSS feed into your favorite feed reader to see when it updates. Just bought the Kindle version. Now I have the book on my Kindle and iPhone Kindle App Looks really crisp on my iphone and has anchor links to each chapter, although it could use a better table of contents Link: ChikkaChiChi on June 27, I just picked this up on AppSumo.
Now on exercise 15! Thanks Zed! Glad you're liking it, and thanks for downloading it. What are the advantages of using this book over the online tutorials that are available on the python website or even using some of the MIT OpenCourseWare courses?
It teaches important life skills in every facet of life: What is the advantage of the course on discount today? The course has 8 I might do more videos where I go through most of the exercises and show you how to do them with tips as I go. You basically get to watch me make mistakes typing the exercises in and learn how I do it. In addition to that I answer questions people ask on the site. The course is on sale at AppSumo: I have not taken the course, but I really liked the first edition book.
I am doing all of it with Python 3. So far, very little needs changing to make the examples work. Very clean and concise. RexRollman on June 27, So this targets an earlier version of Python? Yes, the 2.
I am learning with Python 3 because of a class I am taking and supplementing with Zed's tutorial and just writing the examples in Python 3 format.
So far, so good. I might hit a snag when I get to the web. All of it rolled together is helping me a lot. Yes, and for a reason. Python 3 is still not widely adopted [sic]. Python 3 Wall of Shame: Stop the "wall of shame" shtick, please. It helps nobody. Projects know about Python 3 and projects are planning to move to Python 3.
I could say the same thing about Python programmers, but that's just throwing insults around. I'm pretty sure anyone who did that will be taking early retirement for their RSI.
Java has its place but writing it unassisted is literally physically painful. You don't have to hit enter when you reach the end of the textbox. There is a thing called word wrap. I like python too. Indent level? I can NOT tell you the number of times this has created a bug for me, because the spacing was off. Had one 'flavor' where if you mixed tabs and spaces in the same file one dev liked tabs the other spaces or didnt put tabs on empty lines it would cause the python interpreter to go into lala land.
What is this punch cards? Indent l. I think we all felt that like at the beginning. Now I get really annoyed when I have to use curly braces. Had one 'flavor' where if you mixed tabs and spaces in the same file one dev liked tabs the other spaces or didnt put tabs on empty lines it would cause the python interpreter to go int.
No, the fact the language doesn't deal with the real programmer's life issues with eventually bad text editor, or simply because there will always people with bad or diverging habits is python downside.
The fact that one may or may not use a text editor that you consider "good" or that you think tabs or spaces are the bad way is irrelevant. You may "like it", and I can see why like it's forcing people into doing good indentation , but do not dismiss the issues associated with it. In the same way that the the it is difficult to drive nails into wood with a nail file is the downside of a nail.
Once you apply the correct tool in the correct fashion the problem vanishes. Or Alternatively, I have a "bad habit" I tend on occasion to leave the semi-colon off the end of the line when writing in Perl or C. Thus both Perl and C's "downside" is that they "[don't] with the real programmer's life issues.. I wrote " Are there really programmer's text editors out there that cannot substitute a tab for four spaces throughout a file?!!
You may "like it", and I can see why As it happens I wasn't dismissing the issue, I was offering advice about how anyone still suffering from this issue could dismiss it. Alternatively, I have a "bad habit" I tend on occasion to leave the semi-colon off the end of the line when writing in Perl or C.
The subtle difference being that a semicolon is detectable by the venerable mk1 eyeball, therefore you don't need to apply any of the bandaids you suggest. Yes I agree, the invisibility of different kinds of white space, and not the failure of a language to make allowance for a programmer's bad habits, is the source of this "issue. The issue is trivially dealt with: Set up your tools properly and it ceases to exist. It's quite refreshing to go to a language where as someone with a lot of experience in programming but not much with python with such flexible syntax that "I wonder if I can write it this way?
And as for rapid prototyping it's great. A couple of evenings and or so lines of python and I can have something that would take me weeks in C.
Of course in C I would have had more fine grained control over behaviour and I do run up against barriers in python every so often. The major downside for me is the GIL.
For anything processor intensive you have to work around the language to use the resources of a modern system, rather than work with the language. The multiprocessing package offers both local and remote concurrency, effectively side-stepping the Global Interpreter Lock by using subprocesses instead of threads. Due to this, the multiprocessing module allows the programmer to fully leverage multiple processors on a given machine.
It's a language which has had the misfortunate to be hyped in the past, and co-hyped with Object Oriented Everything. You mistake me. However, I found that with just a very small number of OO-style containers in C, the problem goes away.
Of course most people claiming to understand OO would not be able to do it in a non-OO language.
Having seen some things out of Google, I know that they are not the wizards some people still believe they are by a fairly large margin. You find tremendous arrogance there and you find many fans that take in anything Google without question. A combination of C and OO capable scripting is far more powerful, but requires you to actually know what you are doing on a conceptual not language level.
I have used this approach with very good success and all of Perl, Python and Lua for the scripting. Essentially they became hard to compil.
The thing about abstraction is, if you overdo it, it does not help understanding at all, it just obscures necessary detail.
True, finding the right level of abstraction is more art than science. The experience that I have made doing code review for Java, is that often there is abstraction for abstractions sake and you have to dig through layer after layer until you finally find one where something actually happens. This is hugely counterproductive, makes the code slow, bloated, hard to read and understand.
Well, in my experience, Java is complex as you cannot stay in the core language if you want to get anything done , slow, a memory hog, has inconsistent library interfaces, and cross-platform development requires you to know each platform in question. Eiffel nor scripting as Python, Perl or Lua. It wants to do everything and as a consequence is worse than most other tools at anything. There is a difference between learning and using.
Once they are competent programmers, they can use whatever tool is handy. If the programmer likes fonts and typography, they'll tell you to get a Mac OSX computer. If they like control and have a huge beard, they'll tell you to install Linux. Again, use whatever computer you have right now that works. Philip Greenspun has some good titles: Philip and Alex's Guide to Web Publishing [greenspun. Pro Git [progit. You can download a dead tree version as well. Looks like a good attempt on programming, but if I am starting on Python today, I'd prefer using the current version.
This is a good price-point; yet, if you want to do anything more than an evening with Python, try I have been doing Python 3 for some time. The language is better than Python 2, but you still frequently run into things that are not ported yet. So I would definitely advise either to learn Python 2 and have a look at 3 or the other way round.
For larger projects, I would advise to still use Python 2 at this time, but with a style that allows an automated upgrade later on. This will mean not using some Python 2 features. With features like this it is not suprising that nobody wants to use languages like Java anymore. I loved this website: Totally agree, and the best thing about python is that you usually can get very readable code often with fewer lines than the corresponding alternative you already know.
Much like going from bash to perl on a complicated script, I would say. Yes, the "hard way" doesn't mean it's advanced, it just means you have to type again and again boring things because it's supposed to be a good learning method. Most of this "advice" is bullshit. The "line I've been programming for a very long time.
So long that it's incredibly boring to me. At the time that I wrote this book, I knew about 20 programming languages and could learn new ones in about a day to a week depending on how weird they were. Sure if you've got a background covering C you can pick up those languages based on C syntax pretty quickly - in terms of writing raw statements - but that means very little as most of the heavy lifting these days is done using the supporting libraries.
Sure if by 'picking up' you mean getting to the point of being able to code Quicksort then yes, but otherwise - well I call bullshit. And I've got over 20 years experience and an average of one language a year over that but I'd only claim to really have half a dozen completely understood. I've got over 20 years experience and an average of one language a year over that but I'd only claim to really have half a dozen completely understood.
I've got almost 40 years in, and long ago lost count of languages, operating systems, and hardware environments. You will never have any living computer language "completely understood" for any significant amount of time if you are working on anything more meaningful than simply tracking that language's implementation arc in a worl.
Yes, but to type in the programming exercises, do you recommend using vi or emacs? The author suggests gedit , for all platforms, which is a fair enough suggestion. However he then insists on using spaces over tabs, without any explanation of the relative merits, thus already choosing a side in yet another programming disagreement. A simple "choose one and stick to it" would have sufficed. Sure, either tabs or spaces will work fine, as long as you're consistent.
The problem is that once you move beyond toy programs you will be sharing code with other developers, modifying code you get from other sources, etc. And that other code will use spaces, which means that when you mix your tab-using code with it, stuff will break.
When writing Python, follow the Python community's coding conventions, and one of the strongest and most important is to use spaces, no. I'm a scientific programmer, mostly working on mathematical models and simulation. Almost all the work I do is for myself, and I have very little experience working with others' code. Many of the people I know who use Python are in similar situations. I have personally had far less trouble with tabs than with spaces aesthetically and functionally , and it's what I'm going to continue using until my circumstances change, since Python doesn't care either way only the community, who will never see my code.
I think that believing you'll never have to share code with others is eventually going to cause you great pain. I hope I'm wrong: Neither [learnpytho If a programmer tells you to use vim or emacs, tell them, "No. All you need right now is an editor that lets you put text into a file. We will use gedit because it is simple and the same on all computers.
Cited from http: If they say this, point out to them that Google App Engine originally used web. If it's good enough for Google, then it's good enough for you to get started. Then, just get back to learning to. I went for the ePub version. I perused the chapters from start to end, skimming over all-too familiar ones, and looking at the writing and examples explained. It's a fine read for people new to programming.
It may not be very technically in-depth, may not cover all examples, and it may not warn about all the caveats, but it's a good place nonetheless.
If you already know programming, you might find it a bit slow, and would probably prefer something like Dive Into Python [diveintopython. I have done very little programming other than excel since my college classes in Pascal.
I have gotten to this, "Try more format characters. It's like saying "print this no matter what". Search online for all of the Python format characters. Well, I searched online. I went to http: If it's Kindle, it looks like a good price. The big reason for reading it in that format is precisely to change it, by copying code examples and pasting them into your Python interpreter to see what they do: I just bought it myself, looks great on my Nook.
Chapter 0 of the book has "Make sure you install Python 2 not Python 3. Uhuh, there's a language I want to invest some time in. Is there a reason why the language designers didn't put some kind of versioning into their language when they took the decision that backwards compatibility wasn't important to them?
Some sort of shebang on the first line with the v. So, your post comes down to "I've never used python, let alone programmed in it, but I know enough to insult those who do". Maybe you're the one who can't be bothered to learn something new and are looking to justify that to yourself. Is there a reason why the language designers didn't put some kind of versioning into their language [ It's not difficult. It's your loss. I spent a lot of time learning "proper languages" before getting around to trying Python.
When I finally got around to looking at the language, I regretted not learning it sooner. I was able to both learn the language and write the program that I needed in less time than it would have taken me using the languages I already knew.
Python is a handy tool to have available. Sure, it isn't the best tool for every job, but neither is duct tape. Some sort of shebang on the first line with the version number? The other setup advice, ie.: Change Tab width: Select make sure a check mark is in Insert spaces instead of tabs. Turn on "Automatic indentation" as well. Doesn't inspire me to learn Python either. Why impose a rigid spacing structure on a language in a world where tabs aren't standardized and never will be?
That's only the convention the author is using. Python spacing rules are more flexible than that. If you wanted to really know them you could have googled it a long time ago. As for the rationale again, google it? I know that for some it is an idea that they cannot stomach, but readability as part of the syntax is a good think. And as of why, have you ever had to face code with horrendous indentation or no indentation at all?
Specially when people mix code with mar. Oh, you think watching Python on VHS is the hard way, do you? Why, in my day, if we wanted to see a good Monty Python skit we had to go kidnap the performers, construct a set, and download enough booze to get them drunk enough to perform. I havent looked through all of these to find if there are some that are especially exciting or fun, but the chance at a bit of entry-level creativity is there.
Make it run.
Still too steep?
