Hi, Brendan! I strongly recommend the DataCamp courses. Also, they have free tutorials, cheat sheets, blogs, and podcasts that are really helpful. You can try a 1-month free trial here: https://www.datacamp.com/promo/meetup. More information can be found from these links: http://datacamp.com/, https://www.datacamp.com/community. Recently, I’ve created a list of helpful links for Data Science and Machine Learning, you can find it here: https://tinyurl.com/ybdt29d6. Good luck!
