If you open this page in a new tab, you’ll see some top items. Let's go ahead and extract the top items scraped from the URL: Part 5: Top items being scraped right now # Create seventh_p_text and set it to 7th p element text of the page # Set all_h1_tags to all h1 tags of the soup The solution for this lab is: import requests Create a variable seventh_p_text and store the text of the 7th p element (index 6) inside.select to select all the tags and store the text of those h1 inside all_h1_tags list. This is why you selected only the first element here with the index. select returns a Python list of all the elements. Let's look at an example: import requests That is, you can reach down the DOM tree just like how you will select elements with CSS. select on it which is a CSS selector inside BeautifulSoup. Once you have the soup variable (like previous labs), you can work with. Now that you have explored some parts of BeautifulSoup, let's look how you can select DOM elements with BeautifulSoup methods. Print(page_title, page_head) Part 4: select with BeautifulSoup The solution of this example would be simple, based on the code above: import requests But in reality, when you print(type page_body) you'll see it is not a string but it works fine. When you try to print the page_body or page_head you'll see that those are printed as strings. Let's take a look at how you can extract out body and head sections from your pages. Try to run the example below: import requests text too, and it will give you the full markup. text on these to get the string, but you can print them without calling. It is equally easy to extract out certain sections too. In the last lab, you saw how you can extract the title from the page. This was also a simple lab where we had to change the URL and print the page title. The solution for the lab would be: import requests Looking at the example above, you can see once we feed the ntent inside BeautifulSoup, you can start working with the parsed DOM tree in a very pythonic way. Use BeautifulSoup to store the title of this page into a variable called page_title.Use the requests package to get title of the URL:.Title = # gets you the text of the (.) Passing requirements: Soup = BeautifulSoup(ntent, 'html.parser') Here’s a simple example of BeautifulSoup: from bs4 import BeautifulSoup Beautiful Soup sits on top of popular Python parsers like lxml and html5lib, allowing you to try out different parsing strategies or trade speed for flexibility.īasically, BeautifulSoup can parse anything on the web you give it.It doesn't take much code to write an application It provides a lot of simple methods and Pythonic idioms for navigating, searching, and modifying a DOM tree.Some features that make BeautifulSoup a powerful solution are: In this whole classroom, you’ll be using a library called BeautifulSoup in Python to do web scraping. Part 2: Extracting title with BeautifulSoup Let's move on to part 2 now where you'll build more on top of your existing code. Here's the solution to this lab: import requests Once you understand what is happening in the code above, it is fairly simple to pass this lab. Print txt and status using print function.Store the status code (as shown above) in a variable called status.Store the text response (as shown above) in a variable called txt.Get the contents of the following URL using requests module:.Print(res.status_code) Passing requirements: One example of getting the HTML of a page: import requests The HTTP request returns a Response Object with all the response data (content, encoding, status, and so on). The requests module allows you to send HTTP requests using Python. We will be using Python 3.8 + BeautifulSoup 4 for web scraping. This classroom consists of 7 labs, and you'll solve a lab in each part of this blog post. In this classroom, you'll be using this page to test web scraping: This will be a practical hands-on learning exercise on codedamn, similar to how you learn on freeCodeCamp. If you want to code along, you can use this free codedamn classroom that consists of multiple labs to help you learn web scraping. Introduction to Web Scraping classroom Preview of codedamn classroom Just make sure to check before you scrape. Many companies do not allow scraping on their websites, so this is a good way to learn. Note: We will be scraping a webpage that I host, so we can safely learn scraping on it. We'll also work through a complete hands-on classroom guide as we proceed. In this article, we will cover how to use Python for web scraping. And one exciting use-case of Python is Web Scraping. Python is used for a number of things, from data analysis to server programming. It has a great package ecosystem, there's much less noise than you'll find in other languages, and it is super easy to use. Python is a beautiful language to code in.
