I'm gong to also show you with a practical real-life website, how you can even avoid wasting time on creating a web scraper in the first place, by reverse engineering websites and finding their hidden API's!

Learn how to avoid being blocked from websites when developing out your scraper, by building out the scraper in a test-driven way with mocked html, rather than hitting the website every time as you're debugging and developing it. You'll also learn what you can do if you're blocked and your alternatives to get your scraper up and running regardless!

You will also learn how to scrape on a server with a bad connection, or even if you have a bad connection.

You'll even learn how to save your results to a CSV file and MongoDB!

How do you scrape a site requiring passwords? I'm going to show you that too with a real website (Craigslist)!
