Learn Python The Hard Way. Building a Virtual Python Environment - Akamai Developer Blog. When embarking on a devOps journey, getting a consistent development environment is the key. In this post, I show how to setup a virtual environment and install the correct libraries necessary for a project. A Virtual Environment is a tool to keep the dependencies required by different projects in separate places, by creating virtual Python environments for them.
The tool in python is called virtualenv. To work with isolated environments, the basic steps are as follows: Initial setup: Install the virtualenv tool.Initialize your environmentInstall dependenciesCreate the requirements.txt to remember the dependenciesCheck code and the requirements.txt file into code repository Developer installs: Create virtual environmentGet the latest codeInstall dependenciesStart working on code Let’s step through these in detail. Initial Setup You or one of the developers on your team can kickstart the process by installing the virtualenv tool. source myproject/venv/bin/activate pip install <library file>
Untitled. Any aspiring programmer or current developer looking to move up in the ranks of their current organization should add Python to their resume. Why? Python is a general purpose language that sets a solid foundation for the baseline logic behind all programmatic languages. Beyond that, Python is: 1. Easy to learn Python is an easily readable language, and it has fewer rules and special cases. 2. Python’s maturity as a language means that users have been figuring out new methodologies for its use and debugging it for years. 3. If you’re interested in analytics, Python is the way to go: it’s currently the most popular language to use in conjunction with with data science. 4. Python’s been around for a while – more than two decades, in fact. That includes local and cloud infrastructures, website development, SQL databases, small customized tools, object-oriented design and even AI. If you’re looking to learn Python, a perfect place to start is the Python Programming Bootcamp 2.0.

PY4E - Python for Everybody. Exploring Data In Python 3 New Edition! The goal of this book is to provide an Informatics-oriented introduction to programming. The primary difference between a computer science approach and the Informatics approach taken in this book is a greater focus on using Python to solve data analysis problems common in the world of Informatics. The Python 2 version of the book is still available. There are multiple translations of the Python 2 book - the Python 3 version of the book has not been translated. Updated to use Python 3, the book is now available in a variety of formats: English The sample code and data files for the book is here: Code Samples.
Chapters 2-10 are heavily adapted from the open book titled: "Think Python: How to Think like a Computer Scientist" by Allen B. All of these materials are free and I want you to take them, use them and reuse them. Learning to Program with Python. Here we will use the python programming language to make a game of hangman, starting from scratch, working on a Macintosh. Python comes with OS X, so nothing special needs to be installed to follow along on your Mac. To use python on Windows, you can download and install python here. If you do not want to install python or you want to learn a newer and popular python-like language that runs in any modern browser, you can read Learning to Program with CoffeeScript, at davidbau.com/coffeescript.
The CoffeeScript version of this tutorial adds examples using graphics and synchronization. It takes a couple hours to learn enough programming to make a simple game. We will learn about: Memory and naming Computer arithmetic Using and learning libraries How to make a program Input and output Loops and choices Connecting to the internet At the end we will have a game we can play.

[Python] Massive Python Example Script - General Programming. CHIP - The World's First Nine Dollar Computer by Next Thing Co. Raspberry Pi tem corte no pre�o para competir com concorrente de 9 d�lares. A Raspberry Pi Foundation anunciou nesta quinta-feira (14) um corte no preço do modelo B+ de sua linha de pequenos computadores. Antes vendido por 35 dólares (105 reais), o aparelho sairá agora por 25 dólares (mais ou menos 75 reais) – o que o coloca em pé de igualdade com o “concorrente” CHIP, que apareceu no Kickstarter na última semana e já bateu a meta.
O B+ é o segundo mais avançado entre os Raspberry Pis, mas era vendido pelo mesmo valor de um modelo de segunda geração, mesmo com configurações bem mais modestas. Segundo a fundação, o corte foi possível graças a “otimizações” não especificadas na produção, que tornaram o aparelho “muito mais barato de se fabricar”. Com mais de 5 milhões de unidades vendidas pelo mundo, a linha Raspberry Pi passou a ter concorrentes de peso, como Intel e Imagination, apenas de dois anos para cá.
O corte no preço já vale para revendedoras no exterior, mas parece não ter afetado os valores cobrados por lojas aqui no Brasil. Nbviewer.ipython. Complex Adaptive Systems Modeling | Full text | PyCX: a Python-based simulation code repository for complex systems education. Through several years of experience in complex systems education, we have come to realize that using a simple general-purpose computer programming language itself as a complex systems modeling platform is our current best solution to address most, if not all, of the educational challenges discussed above.
By definition, general-purpose computer programming languages are universal and can offer unlimited opportunity of modeling with all the details clearly spelled out in front of the user’s eyes. Identifying a programming language that would be easily accessible and useful in a wide variety of disciplines had been difficult even a decade ago.a Fortunately, several easy-to-use programming languages have recently emerged and become very popular in various scientific and industrial communities, including Python and R. The core philosophy of PyCX is therefore placed on the simplicity, readability, generalizability and pedagogical values of simulation codes. RD.seed() time = 0 time += 1. 2014 SouthEast LinuxFest - Francois Dion - Brython: Not Celtic, Pythonic! Think Python. A guide to Python Namespaces | The ByteBaker. This post is part of the Powerful Python series where I talk about features of the Python language that make the programmer’s job easier.
The Powerful Python page contains links to more articles as well as a list of future articles. Namespaces are a fundamental idea in Python and can be very helpful in structuring and organizing your code (especially if you have a large enough project). However, namespaces might be a somewhat difficult concept to grasp and get used to if you’re new to programming or even coming from another programming language (in my case, Java). Here’s my attempt to make namespaces just a little easier to understand. What’s in a name? Before starting off with namespaces, you have to understand what Python means by a name. But you can also give names to things like functions: Now whenever you want to use func(), you can use f() instead.
If you accessed the name var in between assignments, you’d get a number, a string and a list at different times. So much for names. Is it hashable? Fun and games with hashing in Python - Lerner Consulting Blog. One of the basic data types that Python developers learn to use, and to appreciate, is the dictionary, or “dict.”
This is the Python term for what other languages call hashes, associative arrays, hashmaps, or hash tables. Dictionaries are pervasive in Python, both in the programs that we write, and in the implementation of the language; behind every namespace or object, at least one dictionary is behind the scenes. Dictionaries are fairly easy to use, once you get used to the rules of the road: A dictionary contains pairs, not individual elements. Each pair has two elements, a “key” and a “value.” So given a dictionary d, len(d) will return the number of pairs, not the number of individual elements.You can think of the key as a sort of index.
To anyone familiar with dicts, or with hash tables in other languages, most of the above rules make a great deal of sense. For example, I can create a simple dictionary: Ruby stores our name-value pair inside of the hash, its equivalent of a dict. The Hitchhiker’s Guide to Python! — The Hitchhiker's Guide to Python. Greetings, Earthling! Welcome to The Hitchhiker’s Guide to Python. This is a living, breathing guide. If you’d like to contribute, fork us on GitHub! This handcrafted guide exists to provide both novice and expert Python developers a best practice handbook to the installation, configuration, and usage of Python on a daily basis. This guide is opinionated in a way that is almost, but not quite, entirely unlike Python’s official documentation. You won’t find a list of every Python web framework available here.
Rather, you’ll find a nice concise list of highly recommended options. Let’s get started! Getting Started with Python New to Python?

Introduction to Python Web Frameworks. So, you’ve learned Python, perhaps using one of the resources you found in our MegaGuide. You’ve built some projects that run on your computer, and now you’re ready to share them with the world online. What’s the next step? If you want to turn your Python project into a web application or a dynamic website, and host it on the Internet for anyone to access, you’re going to need to use a web framework.
You can build your own framework, but as Guido van Rossum, creator of Python, says: “a framework written to serve the needs of a single target application wouldn’t necessarily be better than some of the web frameworks that already exist.” A web framework, also known as a web application framework, is the glue that bonds your project to the server that’s hosting it. It handles many of the common operations associated with web development, including database access, templating, and session management. Let’s start with a list of Python web frameworks commonly used on the Internet today: Django. Probably Overthinking It: Regression with Python, pandas and StatsModels.
I was at Boston Data-Con 2014 this morning, which was a great event. The organizer, John Verostek, seems to have created this three-day event single-handedly, so I am hugely impressed. Imran Malek started the day with a very nice iPython tutorial. The description is here, and his slides are here. He grabbed passenger data from the MBTA and generated heat maps showing the number of passengers at each stop in the system during each hour. The tutorial covered a good range of features, and it seemed like many of the participants were able to download the data and follow along in iPython.
And Imran very kindly let me use his laptop to project slides for my talk, which was next. Regression is a powerful tool for fitting data and making predictions. As an example, I will use data from the National Survey of Family Growth to generate predictions for the date of birth, weight, and sex of an expected baby. This talk is appropriate for people with no prior experience with regression. Learn Python. The History of Python. The Python I Would Like To See. The Python I Would Like To See. Full Stack Python.
