Extracting Structured Data from the Web Using Scrapy from Pluralsight

Data analysts and scientists are always on the lookout for new sources of data, competitive intelligence, and new signals for proprietary models in applications. The Scrapy package in Python makes extracting raw web content easy and scalable.

Websites contain meaningful information which can drive decisions within your organization. The Scrapy package in Python makes crawling websites to scrape structured content easy and intuitive and at the same time allows crawling to scale to hundreds of thousands of websites.

In this course, Extracting Structured Data from the Web Using Scrapy, you will learn how you can scrape raw content from web pages and save them for later use in a structured and meaningful format.

You will start off by exploring how Scrapy works and how you can use CSS and XPath selectors in Scrapy to select the relevant portions of any website. You'll use the Scrapy command shell to prototype the selectors you want to use when building Spiders.

Next, you'll see learn Spiders specify what to crawl, how to crawl, and how to process scraped data.

You'll also learn how you can take your Spiders to the cloud using the Scrapy Cloud. The cloud platform offers advanced scraping functionality including a cutting-edge tool called Portia with which you can build a Spider without writing a single line of code.

At the end of this course, you will be able to build your own spiders and crawlers to extract insights from any website on the web. This course uses Scrapy version 1.5 and Python 3.

Reviews summary

Practical scrapy for web data extraction

Learners say this course offers a solid foundation in web scraping using Scrapy, proving ideal for beginners and those new to the topic. Students consistently praise the clear explanations, knowledgeable instructor, and the course's hands-on approach with practical examples, which significantly aids understanding. The coverage of CSS and XPath selectors is particularly well-regarded. However, some reviewers note that the course uses Scrapy version 1.5, which can lead to compatibility issues or feel outdated for contemporary environments. Additionally, sections on Scrapy Cloud deployment and Portia are described as somewhat superficial, lacking deeper dives into advanced use cases.

Instructor's teaching style and practical labs are highly effective.

"The instructor is knowledgeable and the content is well-structured. Highly recommend it for anyone looking to jump into web scraping."

"I loved the hands-on approach and the way the instructor broke down complex topics into digestible pieces."

"The content is delivered effectively, and the hands-on labs are incredibly helpful. I now have a practical skill I can apply."

Offers a clear, hands-on path to master Scrapy basics.

"This course delivers on its promise. ...provided exactly what I needed to get started quickly and efficiently."

"Excellent course for grasping the fundamentals of Scrapy. The examples are practical and easy to follow. I'm now confident in building my own crawlers."

"I finally understand web scraping thanks to this course! I went from zero knowledge to building functional spiders."

Pace may be slow for experienced users; some setup issues noted.

"It's an okay course, but definitely for beginners only. As someone with prior Python experience, I found the pace a bit slow."

"Found this course somewhat frustrating. The environment setup was a headache..."

"The explanations sometimes assume too much prior knowledge, or jump around too quickly in places. Not ideal for an absolute novice trying to get started without a lot of external research."

Scrapy Cloud and Portia sections could offer more depth.

"I felt that the 'deploying to Scrapy Cloud' part was a bit superficial. It introduces the concept but doesn't go deep enough into best practices..."

"The section on Portia was interesting, but I feel it could have been expanded upon with more real-world examples or use cases."

"While it introduces Scrapy Cloud, I wished there were more detailed examples for deployment and troubleshooting."

Course uses Scrapy 1.5, causing some compatibility challenges.

"The Scrapy 1.5 version used is quite old now. I struggled with some compatibility issues trying to apply it to a newer environment."

"Found this course somewhat frustrating. I encountered several deprecated features with Scrapy 1.5. It feels outdated..."

"My main feedback would be to update the Scrapy version as 1.5 is pretty old now, and some commands or features have changed. This caused some minor headaches during practice."
