Question: If you've learned Python in the last few years, what online resource/website/course was #1 most helpful to you? I'm not looking for lists of lots of resources to learn Python (I know there are a ton!), just your #1 favorite.
The MIT online courses 6.00.1x and 6.00.2x in computational thinking and data science. Intro to CS, data science and Python all in one go, hard to beat that! (For statistics nerds, anyway.)
