Amazon Product Price tracking using Python

Python has powerful libararies, that can do a lot of things in just a few lines of codes.

In this article I'll show you how you can build a program that can track price of any amazon product and let you know if it's price has dropped than a certain value. Let's get started.


Idea here is to load amazon's product page and parse the value of price from html elements of page. Then compare that value with the given value. If it is lower, tell user that price has dropped else, tell price is higher.



Let's implement this approach. For information, I'll use following Python Packages:

  • bs4
  • sys
  • schedule
  • time
  • urllib
  • PyQt5

If you have these packages already installed you are good to go. Otherwise, you can simply install these pckages using follwing command:

pip install package-name

You need to replace package-name with the name of package you want to install.

Once you are done installing all the required packages, you can continue further.



Let's code our idea.

# Amazon product price tracking using Python 
# Get all libs
import bs4 as bs 
import sys 
import schedule 
import time 
import urllib.request 
from PyQt5.QtWebEngineWidgets import QWebEnginePage 
from PyQt5.QtWidgets import QApplication 
from PyQt5.QtCore import QUrl 

class HTMLPage(QWebEnginePage): 

	def __init__(self, url): 
		self.app = QApplication(sys.argv) 
		self.html = '' 

	def _on_load_finished(self): 
		self.html = self.toHtml(self.Callable) 
		print('Load Done.') 

	def Callable(self, html_str): 
		self.html = html_str 

def Amazon_exact_url(url): 
	index = url.find("B0") 
	index = index + 10
	current_url = "" 
	current_url = url[:index] 
	return current_url 

def Amazon_handler(): 
	url = "https://www.amazon.in/Oppo-Aurora-Blue-64GB-Storage/dp/B07PQ7CXLV/"
    # Get url to extract data
	exacturl = Amazon_exact_url(url) 
	ProductPage = HTMLPage(exacturl) 
	soup = bs.BeautifulSoup(ProductPage.html, 'html.parser') 
	js_test = soup.find('span', id ='priceblock_ourprice') 
	if js_test is None: 
		js_test = soup.find('span', id ='priceblock_dealprice')		 
	str = "" 
	for line in js_test.stripped_strings : 
		str = line 

	# To integer 
	str = str.replace(", ", "") 
	current_price = int(float(str)) 
	our_price = 20000
	if current_price < our_price : 
		print("Price Dropped. Get the deal")
		print("Price is high. Bad Deal") 
def TrackerJob(): 

# main Function 
# Here I am checking price every 10 minutes, you can set your own time

while True: 


Load Done.
Price Dropped. Get the deal
