Earlier than beginning, you’ll want to put in the required libraries. These will present the instruments obligatory for internet scraping and information dealing with.

pip set up --quiet -U langchain-scrapegraph pandas

• langchain-scrapegraph: The official package deal for ScrapeGraphAI’s Python instruments.
• pandas: We’ll use this to retailer the leads to a DataFrame or Excel file.

Step 2: Import and Configure Your API Key

To work together with ScrapeGraphAI, you’ll have to arrange your API key. If the important thing isn’t already in your surroundings, you’ll be prompted to enter it securely.

import os
import getpass
import pandas as pd
from langchain_scrapegraph.instruments import SmartScraperTool

# If you have not set your API key in your surroundings, you will be prompted for it:
if not os.environ.get("SGAI_API_KEY"):
    os.environ["SGAI_API_KEY"] = getpass.getpass("ScrapeGraph AI API key:n")

Step 3: Create the SmartScraperTool

This step initializes the ScrapeGraphAI SmartScraper, which serves as the center of the scraping course of.

smartscraper = SmartScraperTool()

This one line of code offers you entry to an AI-based internet scraper that accepts a easy immediate.

Step 4: Write the Immediate

As an alternative of writing traces of CSS or XPath selectors, you inform the software what to do in plain English. For instance:

scraper_prompt = """
1. Go to the Amazon search outcomes web page: https://www.amazon.in/s?okay=bedside+desk
2. For every product itemizing, extract:
   - Product Title
   - Worth
   - Star Score
   - Variety of Rankings
   - Supply particulars
3. Return the outcomes as a JSON array of objects, every with keys:
   "title", "worth", "ranking", "num_ratings", "supply".
4. Ignore sponsored listings if doable.
"""

Be happy so as to add or take away directions. You may additionally embody “product hyperlink” or “prime eligibility.”

Step 5: Invoke the Scraper

With the immediate and scraper prepared, now you can execute the scraping process.

search_url = "https://www.amazon.in/s?okay=bedside+desk"

outcome = smartscraper.invoke({
    "user_prompt": scraper_prompt,
    "website_url": search_url
})

print("Scraped Outcomes:n", outcome)

What you’ll get again is usually an inventory (array) of dictionaries. Every dictionary accommodates the info you requested: title, worth, ranking, num_ratings, supply, and so forth.

Instance (simplified):

[
  {
    "title": "XYZ Interiors Wooden Bedside Table...",
    "price": "₹1,499",
    "rating": "4.3 out of 5 stars",

df = pd.DataFrame(outcome)
df.to_excel("bedside_tables.xlsx", index=False)
print("Knowledge exported to bedside_tables.xlsx")
