Think julia pdf download
In January I started the preparation of a programming course targeting students without programming experience. I wanted to use Julia, but I found that there existed no book with the purpose of learning to program with Julia as the first programming language. I knew the book Think Python by Allen Downey, which contains all the key ingredients to learn to program properly. However, this book was based on the Python programming language.
My first draft of the course notes was a melting pot of all kinds of reference works, but the longer I worked on it, the more the content started to resemble the chapters of Think Python. Soon, the idea of developing my course notes as a port of that book to Julia came to fruition. All the material was available as Jupyter notebooks in a GitHub repository. After I posted a message on the Julia Discourse site about the progress of my course, the feedback was overwhelming.
A book about basic programming think julia pdf download with Julia as the first programming language was apparently a missing link in the Julia universe. It was a bumpy ride. In August Julia v1. Both the toolchain and the example code had think julia pdf download be made Julia v1. I hope you enjoy working with this book, and that it helps you learn to program and think like a computer scientist, at least a little bit.
It is a free and open source programming language. Choosing think julia pdf download programming language is always subjective. For me, the following characteristics of Julia are decisive:. Julia uses multiple dispatch, which allows the programmer to choose from different programming patterns adapted to the application. Julia is an optionally typed programming language whose user-defined data types make the code clearer and more robust, think julia pdf download.
Julia is a unique programming language because it solves the so-called "two languages problem. This does not mean it happens automatically. It is the responsibility of the programmer to optimize the code that forms a bottleneck, but this can done in Julia itself. Used for program listings, think julia pdf download, as well as within paragraphs to refer to program elements such as variable or function names, think julia pdf download, databases, data types, environment variables, statements, and keywords.
If you are not familiar with Git, it is a version control system that allows you to keep track of the files that make up a project, think julia pdf download. A convenience package is provided that can be directly added to Julia.
Both the REPL and a notebook interface are available. If you want to have Julia locally installed on your computer, you can download JuliaPro for free from Julia Computing. It consists of a recent Julia version, the Juno interactive development environment based on Atom, and a number of preinstalled Julia packages. To a local install, you can also add the IJulia package and run a Jupyter notebook on your computer.
I really want to thank Allen for writing Think Python and allowing me to port his book to Julia. Your enthusiasm is contagious! I would also like to thank the technical reviewers for this book, think julia pdf download, who made many helpful suggestions: Tim Besard, Think julia pdf download Janssens, think julia pdf download, and David P.
You forced me to do things right and make this book as original as possible. Thanks to all the students who worked with an early version of this book and all the contributors listed below who sent in corrections and suggestions. If you have a suggestion or correction, please send email to ben. If I make a change based on your feedback, I will add you to the contributor list unless you ask to be omitted. Let me know what version of the book you are working with, and what format.
If you include at least part of the sentence the error appears in, that will make it easy for me to search. Page and section numbers are fine, too, but not quite as easy to work with. Scott Jones pointed out the name change of Void to Nothingand this started the migration to Julia v1. The goal of this book is to teach you to think like a computer scientist. This way of thinking combines some of the best features of mathematics, engineering, and natural science.
Like mathematicians, computer scientists use formal languages to denote ideas specifically computations. Like engineers, they design things, assembling components into systems and evaluating trade-offs among alternatives. Like scientists, they observe the behavior of complex systems, form hypotheses, and test predictions.
The single most important skill for a computer scientist is problem solving. Problem solving means the ability to formulate problems, think creatively about solutions, and express a solution clearly and accurately.
As it turns think julia pdf download, the process of learning to program is an excellent opportunity to practice problem-solving skills. On one level, you will be learning think julia pdf download program, a useful skill by itself.
On another level, you will use programming as a means to an end. As we go along, that end will become clearer, think julia pdf download. A program is a sequence of instructions that specifies how to perform a computation. The computation might be something mathematical, such as solving a system of equations or finding the roots of a polynomial, but it can also be a symbolic computation, such as searching for and replacing text in a document, or something graphical, like processing an image or playing a video, think julia pdf download.
The details look different in different languages, but a few basic instructions appear in just about every language:. So you can think of programming as the process of breaking a large, complex task into smaller and smaller subtasks until the subtasks are simple enough to be performed with one of these basic instructions.
One of the challenges of getting started with Julia is that you might have to install it and related software on your computer. If you are familiar with your operating system, and especially if you are comfortable with the command-line interface, you will have no trouble installing Julia. But for beginners, it can be painful to learn about system administration and programming at the same time. To avoid that problem, I recommend that you start out running Julia in a browser.
In the browser, you can run Julia on JuliaBox. No installation is required—just point your browser there, log in, and start computing see JuliaBox. When it starts, think julia pdf download, you should see output like this:. The first lines contain information about the REPL, so it might be different for think julia pdf download. But you should check that the think julia pdf download number is at least 1. The last line is a prompt that indicates that the REPL is ready for you to enter code.
It displays a result on the screen. The parentheses indicate that println is a function, think julia pdf download. Julia provides operatorswhich are symbols that represent computations like addition and multiplication. You might wonder why the result is A value is one of the basic things a program works with, like a letter or a number.
Some values we have seen so far are 2 These values belong to different types : 2 is an integer Integers belong to the type Int64think julia pdf download belong to Stringand floating-point numbers belong to Float What about values like "2" and " They look like numbers, but they are in quotation marks like strings.
These are strings too:. When you type a large integer, you might be tempted to use commas between groups of digits, as in 1, This is not a legal integer in Julia, but it is legal:. Julia parses 1, as a comma-separated sequence of integers. Natural languages are the languages people speak, such as English, Spanish, and French. They were not designed by people although people try to impose some order on them ; they evolved naturally.
Formal languages are languages that are designed by people for specific applications. For example, the notation that mathematicians use is a formal language that is particularly good at denoting relationships among numbers and symbols. Chemists use a formal language to represent the chemical structure of molecules. And most importantly, programming languages are formal languages that have been designed to express computations. Formal languages tend to have strict syntax rules that govern the structure of statements.
Syntax rules come in two flavors, pertaining to tokens and think julia pdf download. Tokens are the basic elements of the language, such as words, numbers, and chemical elements.
The second type of syntax rule pertains to the way tokens are combined. Similarly, in a chemical formula the subscript comes after the element name, not before, think julia pdf download. This sentence all valid tokens has, but invalid structure with.
When you read a sentence in English or a statement in a formal language, you have to figure out the structure although in a natural language you do this subconsciously. This process is called parsing. Although formal and natural languages have many features in common—tokens, structure, and syntax—there are some differences:.
Natural languages are full of ambiguity, which people deal with by using contextual clues and other information. Formal languages are designed to be nearly or completely unambiguous, which means that any statement has exactly one meaning, think julia pdf download, regardless of context. In order to make up for ambiguity and reduce misunderstandings, natural languages employ lots of redundancy. As a result, they are often verbose.
Formal languages are less redundant and more concise. Natural languages are full of idiom and metaphor.
