Latest Update:March 9, 2017 - Please note that import io is no longer a free program. They just recently started to charge for use of the platform. I would love some feedback about whether to keep the tutorials up for this portion or to remove and add more lessons from Python, Scrapy and/or Ruby. _____________________________________________________________ You'll be web scraping in less than an hour!! This course teaches you three ways to scrape websites: Import. io is a software that you download and is a really quick way to start web scraping quickly. It is not without its limitations but depending on what you need or plan to do it could do everything you need. No programming experience necessary! If you prefer to learn a little programming along the way, and aren't afraid to invest a little time, you can learn how to do web scraping with Ruby and/or Python. Both have their pluses and minuses but both can do just about anything you could imagine. Even if you have never used Python or Ruby you can learn how to still use these programs as a web scraper. But if you are willing to learn you can scrape just about any website there is online! Want to do some web scraping of super popular websites? That's how you will learn!
