4 Best Ways to Learn Web Scraping
When a person copies any piece of information from a website and saves it in another file, they have actually done what a regular web scraper would do. The biggest difference between manual copy-paste and automatic web scraping is that the manual process takes place on a smaller scale. When it comes to web scraping, intelligent and automated automation must be used to extract data from hundreds or even millions of data points.
Web scraping is not something that an ordinary person can easily perform. In order to obtain properly designed, structured and accurate data in line with the web scraping project, it is necessary to be an expert in this field. We at Scrape.do offer you a web scraper tool created by our expert developers.

What You Should Know Before You Start Learning Web Scraping
There are web scrapers available in the form of browser extensions, software, or a cloud-based service that you can access over the Internet. It is quite natural that you do not have any information about which of these web scrapers you want to use and how to use them, there is no need to hesitate. In this section, we told you about the best web scraping libraries you can choose for your project:
- BeautifulSoup: BeautifulSoup, which is the easiest tool you can choose among the libraries and tools we mentioned in this section, also has some disadvantages. When you use BeautifulSoup, you must additionally use a request library to make requests to the website, and you must have a parser to extract data. Because of such features, code transfer between web scraping projects becomes extremely complex.
How Should You Start Learning Web Scraping?
Learning web scraping may seem extremely complicated as there are a lot of programming languages and libraries you can learn, but it is also possible that you can learn it in an easier way. In this section, we’ve given you five different tips on how to get started learning web scraping the easiest.
1. Level Up Starting Easy
If you have decided to create your first scraper to run a web scraping project, you should not lose your enthusiasm by trying to collect the most complex collections of data from the most complex web pages, but instead, you should start with simpler methods.
There are also websites that are specially designed for people to learn web scraping more easily, you should make maximum use of these websites as the sole purpose of these websites is for people to practice. For example, Quotes.toscrape.com would be a good starting practice. However, you should not only use websites designed for web scraping, but after you have mastered the basics of the process, you should go after data that match your interests. If you go after websites that will interest you, you will feel motivated and will enable you to search for new solutions and approaches on your own.
Whatever software language you use, as long as you follow this first recommendation, you will be extremely productive. In addition, this method will be extremely useful for you whether you use a programming language or not. If you want to get used to the basics of books like BeautifulSoup and Scrapy, going very slowly will get better results.
2. Master BeautifulSoup
If you are confident that you have learned the basics, have practiced enough, and have chosen the Python programming language, the next step should be to master the BeautifulSoup library. Mastering BeautifulSoup, a very powerful parsing tool with many different possibilities, can take a long time. After mastering this tool, you will know all the arguments in the find and find_all methods, the concept of parents, children, and siblings, and the attributes in HTML tags as well as an expert software engineer. You will also be able to learn some HTML knowledge after mastering BeautifulSoup.
4. Thoroughly Understand APIs
If you have come this far, we can easily say that you have all kinds of information about scraping websites. However, if you are still not satisfied with where you are and want to improve yourself more, you can try interacting with APIs. API, short for Application Programming Interface, is used by many websites and the general purpose is to connect the front ends of the website to the back ends.
5. Learn About More Tools
Although you know all about web scraping and have done a lot of practice, the truth is that every time you start scraping more complex websites, you will face new challenges to overcome. However, you should not let this make you lose your motivation, because there will be many new tools you can use to meet these challenges.
