Collecting one million website links

I needed a collection of different website links to experiment with Docker cluster. So I created this small script to collect one million website URLs.

Code is available on Github too.

Running script:

Either create a new virtual environment using python3 or use the existing one in your system.
Install the dependencies.

pip install requests, BeautifulSoup

Activate the virtual environment and run the code.

python one_million_websites.py

Complete Code:

import requests
from bs4 import BeautifulSoup
import sys
import time


headers = {
    "Accept": "text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8",
    "Accept-Language": "en-GB,en-US;q=0.9,en;q=0.8",
    "User-Agent": "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Ubuntu Chromium/64.0.3282.167 Chrome/64.0.3282.167 Safari/537.36"
}

site_link_count = 0

for i in range(1, 201):
    url = "http://websitelists.in/website-list-" + str(i) + ".html"
    response = requests.get(url, headers = headers)
    if response.status_code != 200:
        print(url + str(response.status_code))
        continue

    soup = BeautifulSoup(response.text, 'lxml')
    sites = soup.find_all("td",{"class": "web_width"})

    links = ""
    for site in sites:
        site = site.find("a")["href"]
        links += site + "\n"
        site_link_count += 1

    with open("one_million_websites.txt", "a") as f:
        f.write(links)

    print(str(site_link_count) + " links found")

    time.sleep(1)

We are scraping links from site http://www.websitelists.in/. If you inspect the webpage, you can see anchor tag inside td tag with class web_width.

We will convert the page response into BeautifulSoup object and get all such elements and extract the HREF value of them.

Although there is a natural delay of more than 1 second between consecutive requests which is pretty slow but is good for the server. I still introduced a one-second delay to avoid 429 HTTP status.

Scraped links will be dumped in the text file in the same directory.
