Practice your Python Pandas data science skills with problems on StrataScratch! https://www.stratascratch.com/?via=keith In this video we walk through web scraping in Python using the beautiful soup library. We start with a brief introduction to HTML & CSS and discuss what web scraping is. Next we start getting into the basics of the beautiful soup library. This includes how to load a webpage, the basic commands you need to know such as find & find_all, grabbing strings from an HTML elements, etc. The final section of this tutorial is a series of exercises where you can practice your skills. In this section we scrape a webpage for links, we learn how to scrape a table and load it into a pandas dataframe, and we see how you can scrape & download a web image. Hope you enjoy! I’m looking into making future videos on more complex things you can do with web scraping as well as other libraries that are helpful such as Selenium & ScraPy. Subscribe to not miss those.
