You can type in your URL instead of which I randomly typed for an example.
Let’s create a variable ‘res’ to make a request. Next, you have to make a request to the website that you want to scrap. Go to your Python IDLE or Python Shell and let’s write some code.įirst of all, we need to import all three packages.

If you don’t have that in your system, install that too. Generally, ‘ requests’ already come up with Python. If you are on a MAC/Linux, use pip3 instead of pip in the following commands. So go to your command line (CMD) and install them one by one, if you don’t have them already. We need packages like ‘bs4’ which is the beautiful soup, ‘requests’ and ‘lxml’ to proceed. After that, we need to install the necessary packages.

You can also write code in your shell as well if needed. So you should have that ready in your system. I’m using Python IDLE to do the scraping. The next thing you need to do is to get all the necessary tools and packages. Web scraping is all about how you understand the website, its data structures, how things are looking, etc. The first thing you want to do when you are going to do web scraping is to go to the website that you want to scrap and analyze it. Web Scraping using Python’s Beautiful Soup Also, most of the tools of web scraping that are present in the Kali-Linux are being designed in Python.Įnough of the theories, let’s start scraping the web using the beautiful soup library. Python is so fast and easy to do web scraping. Python 3 is the best programming language to do web scraping. But you can’t scrap or crawl someone else’s website, without obtaining their permission. You could scrap your own website for sure. So, make sure you are completely aware of what you are doing, and do web scraping only on legally allowed websites. You have to check the website owner or the policies of the website. Web scraping is not legally allowed on most websites. But sometimes, when the APIs are not available, we go for web scraping. Usually, the ideal way of picking up data from websites is through APIs which is recommended. According to Wikipedia’s definition, web scraping, web harvesting, or web data abstraction is data scraping used for extracting data from websites. When you want to extract some important data from a website, you can use web scraping. It provides a beautiful framework for that called beautiful soup. Python 3 is ridiculously fast in web scraping.
