Ultimate Guide To Scrapy
Last updated on 2018-04-05
About the Book
More and more people are learning web scraping in Python3 but I found out there is no good resources for people to learn Scrapy, which is the most powerful web scraping framework in Python world, considering I have rich experience in this area, so I decide to publish a book to help people, and I plan to continuously add more useful content to this book in future.
The code of many web scraping tutorial soon become unhelpful if the target website changes its structure or implement a new anti-spider policy, which makes reader scratch head and wants somebody who can help them. That is why I include the web scraping exercises in this book, my goal is to try to break down a complex mission such as crawling a bunch of websites to some small tasks so people can try to solve them step by step.
Who is this book for:
This book is for anyone interested in web scraping in Python3
You can get started if you have no tech background.
