Contribute to chris-void/pyway development by creating an account on GitHub. Learn Python the Hard Way is a beginner's programming book written by Zed Shaw. It was written for Python “The Hard Way is Easier” is exactly what they .
In older versions of the book Zed would recommend gedit. The ebook recommends Atom for users of all operating systems which I think is sound advice even if I am an inveterate Emacs user. For a sense of how much detail Zed goes into, he tells you multiple possible names for your terminal program, to add it to your dock, run it, and not to expect it to look like much.
He even includes a screenshot of his example search and the results. Warnings for Beginners Zed warns against some common but faulty programmer advice. I largely agree with him but I think his reasons for doing this bear some explaining.
Practice some charity and ignore the, "for when you are a better programmer" bit. There are two important reasons to take this and the rest of his advice seriously. You cannot conquer all things at once. I do not recommend doing this. Load-balancing your stress levels is important when you are a beginner. Programmers are more frequently pathologically impulsive and self-centered than I have seen in any other profession.
They are not thinking of your needs as a beginner if they tell you to learn Python 3 instead of Python 2. They're just cheering for red team vs. This is not to say I think Zed's necessarily right to teach Python 3 instead of 2.
I don't care My point is that ignoring what programmers tell you is often sound advice. I'd like to go to bed at a reasonable hour tonight and I plan to allot myself only one evening to write this review. This exercise opens with a warning not to skip the front matter and methodological commentary.
I can tell he has paid some attention to how people use the book based on this. The first exercise code opens with a series of print statements. The lines are enumerated in the code block formatting of both versions of the book. The ebook has syntax highlighting, the print version does not.
I can't blame Zed for making the print version monochrome, I've priced what it costs to print a color version of the Haskell Book and it was horrifying.
The ebook version only shows a single screenshot of the code in the Atom text editor. After the picture s of the code in a text editor, both versions of the book show you what running the program should print in a Mac or Windows terminal.
These images seemed identical in both versions of the book. Main thing I noticed is that Zed needs to fix his terminal font and anti-aliasing, but I am petty and finicky about type.
Anticipating a common typographical error in the code, Zed points out where the error might've happened and what the error would look like.
He also anticipates and informs the reader on how to correct a potential problem with ASCII encodings. Exercise 1 is bookended by study drills and common questions asked by students. I was able to understand two of the three drills in Zed's instructions. I'm not sure what Zed was asking for with the first study drill, which is a little worrying as beginners will be using this.
I will assume it's something obvious that I missed.
The common student questions occur at the end of the exercises throughout the book. They are intended to catch failure modes. Zed's approach here is more modular than the Haskell Book.
I think this works because the individual exercises are brief and typically last a handful of pages. In HPFFP we treated it more like a linear stream of consciousness and address anticipated problems in media res. Exercise Zed goes over basic syntactic elements like comments as well as expanding what the learner can do semantically by covering basic arithmetic operations and variables.
The progression here seems more focused on minimizing the novelty of what is introduced syntactically rather than in what is introduced semantically. This is an important pedagogical distinction in the approaches taken by Zed's book and by ours. We ordered the book based on conceptual dependence and difficulty, not on syntactic elements.
Syntax didn't count for nothing, but we believed it was the less difficult category than semantics. Our experience bore this out but I don't think this invalidates Zed's method. To give you an idea of what I mean, here's a snippet of progressions of the code samples: Ex1 print "Hello World!
This means if the reader attempts to copy-pasta the code from the ebook, it'll break. I'm not certain if it was intentional or if it's like our case where we intentionally don't fix things that would make copying and pasting easier. The potential problem with LPTHW here is that someone familiar with unicode might believe they're actually meant to use the fancy quotes and get stuck.
Zed doesn't address it in his student questions section that I could find. The common student questions continue to be a strong point of this book in the potential problems they address. Exercises I will get briefer here as Zed's approach seems consistent and I mostly just want to touch on what the book covers. Zed covers printing in more detail, escape sequences, string concatenation, and requesting manual user terminal input. Exercises These exercises cover getting user input from the arguments passed to the python invocation at the command-line, combining this with input prompts and reading and writing text files.
Getting the length of a string is demonstrated. The code written is still in a scripty top-level style. Exercise 18 This is where defining functions begins. Zed doesn't stage out increasing complexity of function definition. Zed could've showed the user how you can define a parameter-less function that can be invoked multiple times to save on repetition, but chose not to.
Odder still, the gather parameter example is subsumed by a simple two parameter function and the first is called out as useless in the context of the example. Exercises Zed begins by demonstrating the definition of variables along with passing them to functions as arguments. Exercise 18 only demonstrated passing string to functions as arguments. The usual carefulness with progression resumes here. This is followed by using files with functions, functions that return a result, a vocabulary overview, and an exercise in reading code.
Exercise 23 seems careless. The exercise suggests reading whatever Python code you can find on Github, Bitbucket, or Gitorious. There's no real attempt to point people towards things they could understand at that point in the book.
I suspect most readers don't get very far with this. Exercises This sub-sequence begins with practice in writing code from the book which synthesizes the elements you've seen so far. The study drills ask you to describe the elements of the code in a manner not dissimilar from the "parts of speech" you might've done in a language lesson. The help function in the REPL is touched upon. This sub-sequence ends with a quiz where the objective is to fix broken code. I think it would have been better had this exercise been littered throughout the book so that the readers would have more practice doing so.
Approaching this decision charitably, it could be said the readers had enough mistakes of their own to fix, but we chose to have many more exercises in our book. Exercises Boolean logic, truth tables, boolean operators, expressions using boolean operators, and equality.
Followed by if-else statements and guarding blocks of code with if-statements.
Learn Python the Hard Way: A Very Simple Introduction to
The progression is a cumulative synthesis like before. Exercises Loops and lists begin here and is the title of the 32nd exercise.
Appending onto lists, while loops, and indexing into lists are also covered. Exercise 35 This sub-sequence opens with branches within functions. What branch refers to here is the multiple "branches" of code which may or may not execute based on an if statement. The first example combines parameter-less functions, if-else statements, variables, user input, converting an integer from a string, printing, aborting the program, functions calling other functions, an infinite while loop, and having an initial function to kick off a script.
I suspect he's bucking it on purpose since these programs are not intended to be imported by other Python programs. Exercises Debugging the basic process, not a tool , a review of symbols and syntax, reading code, popping and appending to lists, getting the length of a list, splitting strings based on a character divider, and concatenating a list of lists are demonstrated.
Exercise 39 The construction and basic manipulation of Python dictionaries is demonstrated here. The style is imperative and evocative of how the code's been written through the book so far. There has been no lurch into a functional style yet.
Exercises Modules, classes, and objects begin here. Zed touches on Python being referred to as an object-oriented programming language. This is also where import is principally demonstrated. The above quote demonstrates the effort Zed put in to explaining OOP.
Treating modules like dictionaries, invoking functions within modules like methods, accessing top-level variables in a module like a property, and using classes in all these same ways are covered. Object oriented terms qua Python are briefly explained. Exercises This sub-sequence opens with basic object-oriented analysis and design. This is where things get much wordier than they had been up to this point. The objective is to write a simple game engine. The wordiness wouldn't be unusual in some other books, but there's a lot of upfront conceptual mapping and the basic approach isn't demonstrated or justified with any smaller examples.
This would be less jarring if it occurred in almost any other book.
Today Is Zed's Day Off
Eventually Zed has the reader write a bunch of stubbed out classes and empty methods to plan out the API. 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.
It isn't trivial and there is no "shame" in it at all. Planning to download the paperback. While checking out the paperback info, I noticed that the pdf is still free on lulu. Yeah, I changed that. I was trying to give people who bought the paper versions the PDF for free, but lulu considers "free" to mean you get it without downloading the book.Yes, a dict associates one thing to another, no matter what it is.
