Extract all the URLs from the webpage Using Python
Scraping is a very essential skill for everyone to get data from any website. In this article, we are going to write Python scripts to extract all the URLs from the website or you can save it as a CSV file.
Module Needed:
- bs4: Beautiful Soup(bs4) is a Python library for pulling data out of HTML and XML files. This module does not come built-in with Python. To install this type the below command in the terminal.
pip install bs4
- requests: Requests allows you to send HTTP/1.1 requests extremely easily. This module also does not comes built-in with Python. To install this type the below command in the terminal.
pip install requests
Approach:
- Import module
- Make requests instance and pass into URL
- Pass the requests into a Beautifulsoup() function
- Use ‘a’ tag to find them all tag (‘a href ‘)
Example 1:
Python3
import requestsfrom bs4 import BeautifulSoupreqs = requests.get(url)soup = BeautifulSoup(reqs.text, 'html.parser')urls = []for link in soup.find_all('a'): print(link.get('href')) |
Output:
Example 2:
Extracting URLs and save as CSV files.
Python3
import requestsfrom bs4 import BeautifulSoupgrab = requests.get(urls)soup = BeautifulSoup(grab.text, 'html.parser')# opening a file in write modef = open("test1.txt", "w")# traverse paragraphs from soupfor link in soup.find_all("a"): data = link.get('href') f.write(data) f.write("\n")f.close() |
