Overall, it was a good course. I studied Pandas on my own with a book and applied for this course for the purpose of repeated learning and application of Pandas. The Pandas cheat sheet course was actually not that great. It won't be of much help to those who are new to Pandas, new to Python, or very beginners. It's okay as a YouTube video, but it's a bit disappointing as a paid lecture. The Seoul City Corona Analysis course was good. It was a very useful part for me who studied the basics of Pandas because I was able to practice how to process data by applying Pandas to obtain the desired form and results. And the tips given here and there were also very helpful. Like shift-tab, or using ? after a function to see the dot string... I think these are great tips... Summary in one line: I don't recommend it to those who are just starting out with Pandas, but I highly recommend it to those who know a little about Pandas.
