Why did I only see it now.. The instructor seems to have a very neat personality. I always had to open the Jupyter notebook and look at it all the way to the end to know what I did, but it's so convenient that there's an index on the side. And it's good that you keep repeating what you said, so I can review it. Honestly, even though there are various plots, beginners don't know just by hearing the names, but I really like that you apply them one by one, so I can understand them intuitively!!! You're a great instructor for beginners!
