📉 Amazon Price Tracker

This Python script tracks the price of a specific Amazon product and sends an email alert when the price drops below a target amount.

🛠 Files Included

1. amazon_price_tracker.py – The main Python script that performs web scraping and sends email alerts.
2. .env – Stores sensitive data like your email credentials and SMTP server address securely.

⚙️ How It Works

1. Importing Libraries

import smtplib
from bs4 import BeautifulSoup
import requests
import os
from dotenv import load_dotenv

These libraries handle:

• HTTP requests (requests)
• HTML parsing (BeautifulSoup)
• Email sending (smtplib)
• Secure environment variable handling (dotenv)

---

2. Load Environment Variables

load_dotenv()

This loads your credentials and configuration (e.g. email and SMTP server) from a .env file.

---

3. Set Product URL and Request Headers

live_url = "https://www.amazon.in/..."
headers = {
  "User-Agent": "...",
  ...
}

We use a User-Agent header to avoid being blocked by Amazon (they block bots that don’t look like real browsers).

---

4. Scrape the Product Data

response = requests.get(live_url, headers=headers)
soup = BeautifulSoup(response.content, "html.parser")

Makes an HTTP GET request and parses the returned HTML using BeautifulSoup.

---

5. Extract Product Price and Title

price = soup.find(class_="a-price-whole").get_text()
    # We have to remove the comas from between the nos or else the less than operator will not work and it will give str error
price_clean = price.replace(',', '').strip()
price_as_float = float(price_clean)

title = soup.find(id="productTitle").get_text().strip()

• Extracts the price and removes formatting characters like commas
• Converts the price to a float for comparison
• Gets the product name for use in the email

---

6. Compare Price and Send Alert

      # Change the price to what u want to buy, so that u get notified when the price drops.
BUY_PRICE = 1000000
if price_as_float < BUY_PRICE:
    message = f"{title} is on sale for {price}!"

Sends an alert if the product's current price is less than the defined threshold (BUY_PRICE).

---

7. Send Email Notification

with smtplib.SMTP(os.environ["SMTP_ADDRESS"], port=587) as connection:
    connection.starttls()
    result = connection.login(os.environ["EMAIL_ADDRESS"], os.environ["EMAIL_PASSWORD"])
    connection.sendmail(
        from_addr=os.environ["EMAIL_ADDRESS"],
        to_addrs=os.environ["EMAIL_ADDRESS"],
        msg=f"Subject:Amazon Price Alert!\n\n{message}\n{live_url}".encode("utf-8")
    )

This securely logs in to your email account and sends a notification to yourself.

🔐 Example .env File

EMAIL_ADDRESS=youremail@example.com
EMAIL_PASSWORD=yourpassword
SMTP_ADDRESS=smtp.gmail.com

Keep this file private and never commit it to version control (GitHub).
