Before learning new content, it was good to have time to remind myself of what I had learned previously, so that I could check how much I knew about the content. Also, since the code was presented in a storytelling format, it was good because I could clearly understand what I had learned today. In the case of the last scrapy lecture, I was a little disappointed that there was no explanation about the middleware part. I wondered what it would have been like if there had been an example of performing crawling by linking scrapy and selenium through middleware! (This is my extremely personal opinionㅜㅜ). I am really grateful that you provide such high-quality lectures in a systematic way, and as someone working in the field of data science, I can really feel the effort that the instructor put into creating this lecture. I hope you continue to do well!
