Third Edition Page 3. Zed Shaw's Hard Way Series emphasizes instruction and making things as the best way to Learn Python the hard way: a very simple introduction to the terrifyingly beautiful world of computers and. Learn Python the hard way is one of the best books to learn Python today. This article will bring it to you, the lastest edition of Python. 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.

He kept updating it from time to time and eventually Addison-Wesley turned it into a book by the same name and they have now brought it out in its third edition. The website is made up of lots of short exercises that help beginner programmers learn the various nuances of Python but in bite-sized chunks. A DVD with more than 5 hours of tutorial is bundled with the book so that readers also have access to video material. Two things to note before you begin are that the book is on Python 2 and you are warned against installing Python 3. The book is split into 52 exercises or chapters if you will. Most of the chapters are under four pages in length. In fact, there are a lot of chapters that have a blank page between it and the next chapter, so there is some filler going on here.

Then keep reading… Below are 15 free Python eBooks, plus a couple extra, that you can take with you anywhere.

Learn Python the Hard Way

Picking a Python Version: A Manifesto This report guides you through the implicit decision tree of choosing what Python version, implementation, and distribution is best suited for you.

It weighs and discusses the merits of each of these choices, and briefly discusses the reasons each option exists. This report provides a brief yet comprehensive introduction to Python for engineers, researchers, and data scientists who are already familiar with another programming language.

It allows you the opportunity to learn more about your computer system, work with different programs, and even protects your computer and your network against black hat hackers.

The basics of hacking Some of the things that you need to know how to do before hacking Picking out the best hacking tools How to get through passwords on a computer How to do spoofing and man in the middle attacks How to hack through a network or wireless connection How to protect your system and keep it safe Click Here for the Ebook PYTHON: 3 Manuscripts — Python Programming, Hacking Using Python and Linux, and Data Analytics What would you do if you had the power to change the world at your fingertips, and all you had to do was hit enter?

Imagine yourself working at the forefront of emerging technologies that could potentially change millions of lives, and revolutionize the way we think of processing and automation.

This is the reality of our times. 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. 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. Eventually Zed has the reader write a bunch of stubbed out classes and empty methods to plan out the API.

A bit like The mapped out API is correctly described as top-down. This is followed by a listing of all the code that fills in the empty methods and classes for the game engine project. The usual "what you should see" sections and study drills follow. The study drill suggests changing the game, asks you fix a bug he left in the code, asks you to explain a piece of code, adding cheat codes, adding a small combat system, and mentions that the game engine is an example a finite state machine.

He suggests reading about finite state machines on the web even if it might not make sense. It's a little amusing to see these small gestures tossed out when he made little to no effort to point readers to further resources or examples earlier in the book. I suspect this time was different because some of Zed Shaw's open source work entailed extensive use of finite state machines and he has an affectation for them.

Later, inheritance versus composition are covered. Composition here is simple methods-invoking-other-methods. He strongly recommends against using multiple inheritance. Nothing too objectionable here. Exercise 45 The reader is asked to make their own game like the space game that was just demonstrated.

There's a lot of commentary on code style and syntactic elements. There's no attempt at ameliorating the blank-slate problem for beginners making a project from scratch.

Exercises Project structure, automated testing with assertions, nosetests, exceptions very briefly , basic text processing with a lexicon, and basic parsing are covered.

Note that the first time exceptions were called out by name was in the overview of symbols but he's been using try off and on throughout the book. Exercises Making a basic web application with web. As you might imagine, the explanations of what makes a web app tick are briefly but my coauthor and I are no less guilty of this. It's a huge topic. Exercise 52 The task in this exercise is to refactor the game from exercise 43 into a web application. This covers the basics of refactoring code and web sessions.

The reader is expected to do most of the work this time, including figuring out how to make user authentication work. This one seems like a leap based on how much handholding there had been in the book so far. I felt uncomfortable with the final project in our book because it expects the reader to learn TCP sockets on their own, but I think the lacuna was not so bad there.

Zed's Commentary The book includes two bits of commentary separating the 52nd exercise and the content that goes over the command line. One is called "Next Steps" has a couple subsections. The first subsection of "Next Steps" is an overview of how to go deeper with Python, particularly in specific domains like data analysis. I believe this is partly because Zed is trying to empower people whose principal "job" isn't software itself but which might by augmented by knowing how to code.

The second subsection is titled, "How to learn any programming language. This is the content I noted had a very different presentation in the table of contents of the print and ebook variants of LPTHW. The sequence introduces individual command line applications and builds on them iteratively. I assume he is attempting to be funny, but he comes across as snarky, at best. Regardless of whether you enjoy that type of writing, the core content is pretty good.

I think beginners will benefit from the book. Facebook Comments. Previous Article Skype now has a new feature that helps conduct technical and coding interviews. This comment form is under antispam protection. Most reacted comment. Hottest comment thread. Recent comment authors. Notify of.
