Teacher! Wow~ I finally finished the second crawling lecture. After finishing the first lecture, I gained momentum and finished the second lecture quickly. It's really fun to see all kinds of knowledge coming into my head and merging them. Actually, I'm a graduate student studying machine learning and deep learning, but I feel like I lack basic knowledge to be a data analyst, so I'm taking the lectures according to the roadmap. Now, I need to quickly listen to and internalize mySQL and NoSQL, and then move on to Pandas. Thank you for the great lecture!
