Python Tutorial: Web Scraping with BeautifulSoup and Requests

description
In this Python Programming Tutorial, we will be learning how to scrape websites using the BeautifulSoup library. BeautifulSoup is an excellent tool for parsing HTML code and grabbing exactly the information you need. So whether you're pulling down headlines from news sites, scores from sports websites, or prices from an online store... BeautifulSoup and Python will help you get this done quickly and easily. Let's get started...
