Python Amazon price tracker
Amazon Price tracker
In
this article, we are going to build out a project using python. If you
are a python beginner or learning web scraping this simple application
will give you some good practice.
we
are going to create a script that will track the price of an item and
whenever the price of that item falls below the level you want, the
script will send you an email. you can choose any product from any
website to track using this script.
Requirements:
PythonBeautiful Souppip install bs4Requestspip install requests
firstly we are going to import the required libraries, and we will provide the link to the product you want to track.
import requests
from bs4 import BeautifulSoup
import smtplib
import time
URL = 'url of the product'Note: Not every website allows web scraping
Now,
we will define headers which will be a dictionary"User-Agent" and
provide your browser's user agent details, you can search your
user-agent by typing my user agent on google, and load the page using
"requests.get()" method.
headers = {"User-Agent": 'your-browser-user-agent'}
page = requests.get(URL, headers=headers)We will extract now useful information using Beautiful Soup and then extract the name and the price of our item using the id.
soup = BeautifulSoup(page.content, 'html-parser')
title = soup.find(id="productTitle").get_text()
price = soup.find(id="pricebloc_ourprice").get_text()
converted_price = float(price[0:5])Now
we will wrap all this inside a function and make a condition statement
so that whenever the price falls in that range the script sends the
email.
def check_price():
page = requests.get(URL, headers=headers)
soup = BeautifulSoup(page.content, 'html-parser')
title = soup.find(id="productTitle").get_text()
price = soup.find(id="pricebloc_ourprice").get_text()
converted_price = float(price[0:5])
if(converted_price < "your_price"):
sendmail()Now,
we will define "sendmail()" function which will sen us an email
whenever the price drops and reaches below our defined limit. to perform
this function enable the two-step verification of your email
def sendmail():
server = smtlib.SMTP('smtp.gmail.com', 587)
servor.ehlo()
server.starttls()
server.ehlo()
server.login('username@gmail.com', 'password')
subject = 'Price fell down'
body = 'check the link (link)'
msg = f"Subject: {subject}\n\n{body}"
server.sendmail('username@gmail.com', msg)
server.quit()Next, we create a while loop that runs indefinitely and calls check_price function after every hour
while(True):
check_price()
time.sleep(60 * 60)FULL CODE:
import requests
from bs4 import BeautifulSoup
import smtplib
URL = 'url of the product'
headers = {"User-Agent": 'your-browser-user-agent'}
def check_price():
page = requests.get(URL, headers=headers)
soup = BeautifulSoup(page.content, 'html-parser')
title = soup.find(id="productTitle").get_text()
price = soup.find(id="pricebloc_ourprice").get_text()
converted_price = float(price[0:5])
if(converted_price < "your_price"):
sendmail()
def sendmail():
server = smtlib.SMTP('smtp.gmail.com', 587)
servor.ehlo()
server.starttls()
server.ehlo()
server.login('username@gmail.com', 'password')
subject = 'Price fell down'
body = 'check the link (link)'
msg = f"Subject: {subject}\n\n{body}"
server.sendmail('username@gmail.com', msg)
server.quit()
while(True):
check_price()
time.sleep(60 * 60)
