We now have python requests library and beautiful soup installed.

Let us now write the code, that will scrap the data from the URL given.

Web scraping

import requests
from bs4 import BeautifulSoup
res = requests.get('https://www.tutorialspoint.com/tutorialslibrary.htm')
print("The status code is ", res.status_code)
print("\n")
soup_data = BeautifulSoup(res.text, 'html.parser')
print(soup_data.title)
print("\n")
print(soup_data.find_all('h4'))

Using requests library, we can fetch the content from the URL given and beautiful soup library helps to parse it and fetch the details the way we want.

You can use a beautiful soup library to fetch data using Html tag, class, id, css selector and many more ways. Following is the output we get wherein we have printed the title of the page and also all the h4 tags on the page.
