As we know Python is a multi-purpose language and widely used for scripting. We can write Python scripts to automate daily life task.
Let’s say we want to track any Amazon product price and grab the deal when the price changes below our defined price. Let’s write a Python script for this.
Below is the code:
# Amazon product price tracker using Python # importing libraries 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 import winsound frequency = 2500 # Set Frequency To 2500 Hertz duration = 1000 # Set Duration To 1000 ms == 1 second class Page(QWebEnginePage): def __init__( self , url): self .app = QApplication(sys.argv) QWebEnginePage.__init__( self ) self .html = '' self .loadFinished.connect( self ._on_load_finished) self .load(QUrl(url)) self .app.exec_() def _on_load_finished( self ): self .html = self .toHtml( self . Callable ) print ( 'Load finished' ) def Callable ( self , html_str): self .html = html_str self .app.quit() def exact_url(url): index = url.find( "B0" ) index = index + 10 current_url = "" current_url = url[:index] return current_url def mainprogram(): exacturl = exact_url(url) # main url to extract data page = Page(exacturl) soup = bs.BeautifulSoup(page.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 # convert to integer str = str .replace( ", " , "") current_price = int ( float ( str )) your_price = 600 if current_price < your_price : print ( "Price decreased book now" ) winsound.Beep(frequency, duration) else : print ( "Price is high please wait for the best deal" ) def job(): print ( "Tracking...." ) mainprogram() # main code schedule.every( 1 ).minutes.do(job) while True : schedule.run_pending() time.sleep( 1 ) |
Output:
Tracking.... Load finished Price is high please wait for the best deal
