This book provides a complete and modern guide to web scraping, using Python as the programming language, without glossing over important details or best practices. Written with a data science audience in mind, the book explores both scraping and the larger context of web technologies in which it operates, to ensure full understanding. The authors recommend web scraping as a powerful tool for any data scientist’s arsenal, as many data science projects start by obtaining an appropriate data set. Starting with a brief overview on scraping and real-life use cases, the authors explore the core concepts of HTTP, HTML, and CSS to provide a solid foundation. Along with a quick Python primer, they cover Selenium for JavaScript-heavy sites, and web crawling in detail. The book finishes with a recap of best practices and a collection of examples that bring together everything you've learned and illustrate various data science use cases. What You'll Learn Leverage well-established best practices and commonly-used Python packages Handle today's web, including JavaScript, cookies, and common web scraping mitigation techniques Understand the managerial and legal concerns regarding web scraping Who This Book is For A data science oriented audience that is probably already familiar with Python or another programming language or analytical toolkit (R, SAS, SPSS, etc). Students or instructors in university courses may also benefit. Readers unfamiliar with Python will appreciate a quick Python primer in chapter 1 to catch up with the basics and provide pointers to other guides as well.

Successfully scrape data from any website with the power of Python About This Book A hands-on guide to web scraping with real-life problems and solutions Techniques to download and extract data from complex websites Create a number of different web scrapers to extract information Who This Book Is For This book is aimed at developers who want to use web scraping for legitimate purposes. Prior programming experience with Python would be useful but not essential. Anyone with general knowledge of programming languages should be able to pick up the book and understand the principals involved. What You Will Learn Extract data from web pages with simple Python programming Build a threaded crawler to process web pages in parallel Follow links to crawl a website Download cache to reduce bandwidth Use multiple threads and processes to scrape faster Learn how to parse JavaScript-dependent websites Interact with forms and sessions Solve CAPTCHAs on protected web pages Discover how to track the state of a crawl In Detail The Internet contains the most useful set of data ever assembled, largely publicly accessible for free. However, this data is not easily reusable. It is embedded within the structure and style of websites and needs to be carefully extracted to be useful. Web scraping is becoming increasingly useful as a means to easily gather and make sense of the plethora of information available online. Using a simple language like Python, you can crawl the information out of complex websites using simple programming. This book is the ultimate guide to using Python to scrape data from websites. In the early chapters it covers how to extract data from static web pages and how to use caching to manage the load on servers. After the basics we'll get our hands dirty with building a more sophisticated crawler with threads and more advanced topics. Learn step-by-step how to use Ajax URLs, employ the Firebug extension for monitoring, and indirectly scrape data. Discover more scraping nitty-gritties such as using the browser renderer, managing cookies, how to submit forms to extract data from complex websites protected by CAPTCHA, and so on. The book wraps up with how to create high-level scrapers with Scrapy libraries and implement what has been learned to real websites. Style and approach This book is a hands-on guide with real-life examples and solutions starting simple and then progressively becoming more complex. Each chapter in this book introduces a problem and then provides one or more possible solutions.

Tiny House, Large Lifestyle! Tiny homes are popping up across America, captivating people with their novel approach not only to housing, but to life. Once considered little more than a charming oddity, the tiny house movement continues to gain momentum among those who thirst for a simpler, "greener," more meaningful life in the face of society's "more is better" mindset. This book explores the philosophies behind the tiny house lifestyle, helps you determine whether it's a good fit for you, and guides you through the transition to a smaller space. For inspiration, you'll meet tiny house pioneers and hear how they built their dwellings (and their lives) in unconventional, creative and purposeful ways. They'll invite you in, show you around their cozy abodes, and share lessons they learned along the way. Inside you'll find everything you need to design a tiny home of your own: Worksheets and exercises to help you home in on your true needs, define personal goals, and develop a tiny house layout that's just right for you. Practical strategies for cutting through clutter and paring down your possessions. Guidance through the world of building codes and zoning laws. Design tricks for making the most of every square foot, including multi-function features and ways to maximize vertical space. Tours of 11 tiny houses and the unique story behind each. Tiny House Living is about distilling life down to that which you value most...freeing yourself from clutter, mortgages and home maintenance...and, in doing so, making more room in everyday life for the really important things, like relationships, passions and community. Whether you downsize to a 400-square-foot home or simply scale back the amount of stuff you have in your current home, this book shows you how to live well with less.
