-The installation and environment setup parts were difficult. The lecture content wasn't detailed enough, and because of that, I had to search Google or Naver to fix errors. -It would have been good if you had mentioned at the beginning of the lecture that signing up for Naver Clova Studio or ChatGPT services incurs charges... You mentioned it later, so I had the hassle of having to cancel the payment. 😭..😭 -From lecture 9 onwards, the difficulty level suddenly increased and I couldn't understand the class content well. Especially the part at the end where you automatically complete and deploy a blog... -Overall it was helpful, but it seems there's still some distance to go before being able to create something with streamlit using python.
