Basic Web Scraping Python



Web scraping with Python is easy due to the many useful libraries available. A barebones installation isn’t enough for web scraping. One of the Python advantages is a large selection of libraries for web scraping. For this Python web scraping tutorial, we’ll be using three important libraries – BeautifulSoup v4, Pandas, and Selenium. Check out the tutorial on how to scrape dynamic web pages with Python. Learn how to extract data with Selenium, headless browsers, and the web scraping API. Skip to main content. To demonstrate the basic idea of a dynamic website, we can create a web page that contains dynamically rendered text.

Python makes it simple to grab data from the web. This is a guide (or maybe cheat sheet) on how you can scrape the web easily with Requests and Beautiful Soup 4.

Learn web scraping in Python using the BeautifulSoup library; Web Scraping is a useful technique to convert unstructured data on the web to structured data; BeautifulSoup is an efficient library available in Python to perform web scraping other than urllib; A basic knowledge of HTML and HTML tags is necessary to do web scraping in Python.

Getting started

First, you need to install the right tools.

These are the ones we will use for the scraping. Create a new python file and import them at the top of your file.

Fetch with Requests

What Is Web Scraping

The Requests library will be used to fetch the pages. To make a GET request, you simply use the GET method.

You can get a lot of information from the request.

To be able to scrape your page, you need to use the Beautiful Soup library. You need to save the response content to turn it into a soup object.

You can see the HTML in a readable format with the prettify method.

Now to the actual scraping. Getting the data from the HTML code.

Using CSS Selector

The easiest way is probably to use the CSS selector, which can be copied within Chrome.

Here, I have selected the first Google result. Inspected the HTML. Right clicked the element, selected copy and choose the Copy selector alternative.

Python

The select element will, however, return an array. If you only want one object, you can use the select_one method instead.

Using Tags

You can also scrape by tags (a, h1, p, div) with the following syntax.

It is also possible to use the id or class attribute to scrape the HTML.

Using find_all

Web Scraping Tools

Another method you can use is find_all. It will basically return all elements that match.

You can also use the find method, which will return a single element instead of an array.

Get the values

The most important part of scarping is getting the actual values (or text) from the element.

Get the inner text (the actual text printed on the page) with this method.

If you want to get a specific attribute of an element, like the href, use this syntax:
