This is the level of self-study of data analysis using Python for a year 3 years ago. (Beginner~Beginner level) I came across this lecture when I was about to start studying again for stock analysis after giving up on it for a living. I've only listened to half of it, but the more I listen, the more I think about how great it would have been if I had known about this lecture 3 years ago, so I'm leaving a review in advance. Come to think of it, this lecture wasn't available 3 years ago. ㅠ It was the best to listen to it now. It's a great lecture that makes you feel the need to study formally while listening to the basics and various tips necessary for analysis, and even the concept of unit testing in data analysis. I regret that my expressive skills are lacking. It's a life lecture. Lastly, if you have time, please make a lecture on financial information crawling, automatic trading system, and reinforcement learning utilization into a lecture. Stay healthy in the cold winter~ Be happy. Thank you.
