This is exactly the lecture I wanted. It's a combination of data + maps. Thanks to the instructor, I got TOEIC ideas and learned about a useful library called Folium. I kept forgetting because I only learned the language and didn't use it, but it was definitely fun and memorable after practicing. If I have one wish, I hope there are more lectures like this one where you study the core grammar of Python or other languages and then practice them simply. Thank you^^
