The need and importance of extracting data from the web is becoming increasingly loud and clear. There is an unprecedented volume of data on the internet right now - and data science projects often need this data to build predictive models.
That’s a key reason why data scientists are expected to be familiar with web scraping.
We have found web scraping to be a very helpful technique for gathering data from multiple websites. Some websites these days also provide APIs for many different types of data you might want to use, such as Tweets or LinkedIn posts.
But there might be occasions when you need to collect data from a website that does not provide a specific API. This is where having the ability to perform web scraping comes in handy. As a data scientist, you can code a simple Python script and extract the data you’re looking for.
So knowing how to perform web scraping using Python will help you go a long way towards becoming a resourceful data scientist. Are you ready to take the next step and dive in?
A note of caution here – web scraping is subject to a lot of guidelines and rules. Not every website allows the user to scrape content so there are certain legal restrictions at play. Always ensure you read the website’s terms and conditions on web scraping before you attempt to do it.
In this course, we will dive into the basics of web scraping using Python. We will understand what web scraping is, the different Python libraries for performing web scraping, and finally we’ll implement web scraping using Python in a real-world project. There’s a lot to unpack here so enroll today and start learning!
We’re sure you’ve asked these questions before. Even if you haven’t, you should start learning how these web scraping questions should be answered:

What is web scraping?
Web scraping is a computer software technique of extracting information from websites. This technique mostly focuses on the transformation of unstructured data (HTML format) on the web into structured data (database or spreadsheet).
You can perform web scraping in various ways, including use of Google Docs to almost every programming language.
Why should you learn web scraping?
Web scraping is incredibly useful when you don’t have enough data with you to train a machine learning model. Web scraping helps us to collect this data from websites (if permitted) and we can then use that to train our model. You can imagine why web scraping is such a prized tool in a data scientist’s arsenal!
Why Python for web scraping?
Python is the most popular tool out there in the world for Web Scraping. Its 2 prominent libraries - BeautifulSoup and Scrapy makes web scraping easy and efficient. Python’s syntax makes understanding of the codes easy. Also python provides many other libraries for web scraping which can be used as per our needs. Eg- lxml, requests etc
What are the different Python libraries for performing web scraping?
There are many libraries in Python that help us to scrape the web. The 3 most prominent libraries include:
Can I use R for web scraping?
You sure can! You can perform web scraping in both Python and R. We are teaching you how to do this using Python in the course but feel free to use R if that’s your language of choice. You can go through this tutorial that walks you through how to master web scraping using an R package called rvest.
Are web scraping concepts asked in data science/machine learning interviews?
This depends a lot on the data science role and the organization you’re interviewing for. Not all organizations require you to know or apply web scraping. But here’s why you should learn it anyway - it will help you expand your skillset and also help you work on your personal projects for data science. There’s a lot to learn and nothing to lose!
