Web scraping is the process of extracting data from websites automatically. Whether you’re gathering product prices, news headlines, or social media metrics, Python’s simplicity and powerful libraries make it the go-to language for beginners and professionals alike.
In this tutorial, we’ll walk through the fundamentals, show you how to install the necessary libraries, and provide three practical code examples.
---
pip install requests beautifulsoup4 lxml
**Tip:** If the target site relies heavily on JavaScript, consider adding **Selenium** or **Playwright** to your toolkit.
---
import requests
url = "https://example.com"
response = requests.get(url)
html_content = response.text
from bs4 import BeautifulSoup
soup = BeautifulSoup(html_content, "lxml")
titles = soup.select("h2.title")
for title in titles:
print(title.get_text(strip=True))
This simple script pulls all <h2 class="title"> elements from a static page.
---
Many websites split data across several pages. Below is a generic loop that follows “Next” links until no more pages remain.
base_url = "https://example.com/articles?page="
page = 1
all_titles = []
while True:
response = requests.get(f"{base_url}{page}")
soup = BeautifulSoup(response.text, "lxml")
titles = soup.select("h2.title")
if not titles:
break
for title in titles:
all_titles.append(title.get_text(strip=True))
page += 1
print(f"Collected {len(all_titles)} titles.")
---
If a site renders data via JavaScript, requests alone won’t capture it. Selenium automates a real browser.
pip install selenium webdriver-manager
from selenium import webdriver
from webdriver_manager.chrome import ChromeDriverManager
driver = webdriver.Chrome(ChromeDriverManager().install())
driver.get("https://example.com/dynamic")
# Wait for JavaScript to load (simple sleep for demo purposes)
import time
time.sleep(3)
page_source = driver.page_source
soup = BeautifulSoup(page_source, "lxml")
data = soup.select("div.dynamic-content")
for item in data:
print(item.get_text(strip=True))
driver.quit()
**Pro Tip:** Use `WebDriverWait` for more reliable waits.
---
1. Check the robots.txt – Ensure you’re allowed to crawl.
2. Rate limit – Add delays (time.sleep(1)) between requests.
3. User-Agent – Identify your bot responsibly.
headers = {"User-Agent": "MyScraperBot/1.0 (+https://mywebsite.com)"}
response = requests.get(url, headers=headers)
---
Once you have the data, decide how to store it:
Example: Writing to CSV.
import csv
with open("scraped_titles.csv", "w", newline="", encoding="utf-8") as f:
writer = csv.writer(f)
writer.writerow(["Title"])
for title in all_titles:
writer.writerow([title])

Use rotating proxies, add realistic delays, and respect the site’s robots.txt. Switching user agents and randomizing request headers also helps.
Yes, but it’s more complex. Use requests.Session() to maintain cookies or Selenium to automate the login flow. Always verify you have permission to access the data.
Maintain a robust selector strategy (e.g., XPath with stable attributes). Write tests that alert you when selectors break, and keep the scraping logic modular for easy updates.

With Python’s rich ecosystem, web scraping is accessible to beginners while powerful enough for advanced users. Start by mastering the basics, respect ethical guidelines, and experiment with more sophisticated tools like Scrapy or Playwright. Happy scraping!
