headers = {"User-Agent": "Your User Agent"}

response = requests.get(url, headers=headers)

Use `BeautifulSoup` or `lxml` to parse the HTML content of the page and extract the product data you need.

from bs4 import BeautifulSoup

soup = BeautifulSoup(response.text, 'html.parser')

# Extract data using BeautifulSoup's methods
product_title = soup.find('h1', class_='product-title').text
product_price = soup.find('span', class_='product-price').text
# ...

# You might need to explore the HTML structure and adapt this code to your specific case.

Extract Data

Use the parsed HTML to extract the desired product information, such as title, price, description, reviews, etc. You must inspect the HTML and use the appropriate tags and attributes to locate and extract the data.

Store Data

Depending on your requirements, store the scraped data in a suitable format, such as a CSV file, JSON, or database.
