Learn how to extract all links from any website in Python
In this tutorial, you’re going to learn how to extract all links from a given website or URL using BeautifulSoup and requests.
If you’re new to web scraping I would recommend starting first with the article beginner tutorial to Web scraping and then move to this one once you get comfortable with the basics.
how do we extract all links?
We will use the requests library to get the raw HTML page from the website and then we are going to use BeautifulSoup to extract all the links from the HTML page.
To follow through with this tutorial you need to have requests and Beautiful Soup library installed.
$ pip install requests
$ pip install pip install beautifulsoup4
Below is a code that will prompt you to enter a link to a website and then it will use requests to send a GET request to the server to request the HTML page and then use BeautifulSoup to extract all link tags in the HTML.
import requestsfrom bs4 import BeautifulSoupdef extract_all_links(site): html = requests.get(site).text soup = BeautifulSoup(html, 'html.parser').find_all('a') links = [link.get('href') for link in soup] return linkssite_link = input('Enter URL of the site : ')all_links = extract_all_links(site_link)print(all_links)
Now once you run the above script it will produce result similar to what shown below
kalebu@kalebu-PC:~/$ python3 link_spider.py Enter URL of the site : https://kalebujordan.com/ ['#main-content', 'mailto://email@example.com', 'https://web.facebook.com/kalebu.jordan', 'https://twitter.com/j_kalebu', 'https://kalebujordan.com/'
