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.

In a world of rising tensions between Russia and the United States, the Middle East and Europe, Sunnis and Shiites, Islamism and liberalism, Turkey is at the epicentre. And at the heart of Turkey is its right-wing populist president, Recep Tayyip Erdo?an. Since 2002, Erdo?an has consolidated his hold on domestic politics while using military and diplomatic means to solidify Turkey as a regional power. His crackdown has been brutal and consistent - scores of journalists arrested, academics officially banned from leaving the country, university deans fired and many of the highest-ranking military officers arrested. In some senses, the nefarious and failed 2016 coup has given Erdo?an the licence to make good on his repeated promise to bring order and stability under a 'strongman'. Here, leading Turkish expert Soner Cagaptay will look at Erdo?an's roots in Turkish history, what he believes in and how he has cemented his rule, as well as what this means for the world. The book will also unpick the 'threats' Erdogan has worked to combat - from the liberal Turks to the Gulen movement, from coup plotters to Kurdish nationalists - all of which have culminated in the crisis of modern Turkey.
